Frequently Asked Questions (FAQs)
Q. After polishing the aluminium on my aircraft with the NuShine products, what is the best product to use, which is tested and approved, to apply onto the surface to protect it from corrosion? I have tried the existing approved products, they last a few days after which I need to repolish the aircraft abrightwork.
A. Nuvite have recently released Skyde Clear, it has been tested by Gulfstream as the existing approved product offered very little to no protection at all. Working with Gulfstream, Nuvite developed Skyde Clear. Testing by Gulfstream showed that the Skyde Clear provided protection for 6 months, during this time only cleaning was required. Skyde Clear offeres significanly more protection and reduced costs considerably. For more information, visit our product page HERE. There is a bit more information on the Nuvite website HERE.
Q. If I find bedbugs inside my aircraft which I believe is quite common, is there a product I can use to get rid of them?
A. Bed bugs can be found on aircraft, but it is relatively rare. Bed bugs are small, reddish-brown insects that feed on the blood of humans and animals. They are known to infest places where people congregate or spend extended periods of time, and this can include airplanes. Bed bugs are often associated with hotels, hostels, and other accommodations, but they can also be transported on luggage and clothing, making it possible for them to infest aircraft as well.
Aircraft are generally cleaned and inspected regularly, and airlines take measures to prevent and address bed bug infestations. However, it’s still possible for passengers to unknowingly carry bed bugs onto a plane, and these pests can hide in luggage or personal belongings.
If you suspect you have encountered bed bugs on an aircraft or in your travels, it’s important to notify the airline or relevant authorities so that appropriate action can be taken to address the issue. Travelers should also take precautions, such as inspecting hotel rooms and their luggage, to minimize the risk of bringing bed bugs home with them.
Our Bacoban for Aerospace is effective against bedbugs. Tested in a laboratory in Germany, Bacoban for Aerospace was found to have a kill rate of between 80 and 100 percent when the area was fogged with our 3% solution. The test method used was BPD BioG 005-02.
Q. What are the main parameters when diluting concentrated cleaning chemicals for use when cleaning aircraft?
A. When diluting concentrated cleaning chemicals for cleaning aircraft, several main parameters should be taken into consideration. These parameters include:
Concentration: The initial concentration of the aviation approved cleaning chemical is a crucial factor when diluting it. It determines the strength and effectiveness of the solution. The concentration is typically indicated on the product label or technical datasheet.
Desired Dilution Ratio: The desired dilution ratio specifies the proportion of the concentrated cleaning chemical to be mixed with a diluent (usually water) to achieve the desired strength. For example, a dilution ratio of 1:10 means mixing one part of the concentrate with ten parts of water.
Safety Precautions: Diluting cleaning chemicals often involves handling potentially hazardous substances. It is essential to follow safety precautions such as wearing appropriate personal protective equipment (PPE), working in a well-ventilated area, and avoiding contact with skin or eyes.
Container Size: The size of the container used for dilution determines the total volume of the diluted solution. Consider the appropriate container size based on the amount of diluted solution needed and the mixing ease.
Mixing Technique: Dilution should be done using proper mixing techniques to ensure a uniform distribution of the concentrate in the diluent. This can involve stirring, shaking, or using mechanical mixing equipment, depending on the volume and characteristics of the cleaning chemical.
Water Quality: The quality of the water used for dilution can affect the performance of the cleaning solution. Hard water with high mineral content may reduce the effectiveness of some cleaning chemicals. In such cases, using distilled or demineralized water is recommended.
Storage and Labeling: Properly label the diluted solution with the product name, dilution ratio, date of preparation, and any necessary warnings. Store the diluted solution in a labeled, tightly sealed container, away from direct sunlight and heat sources.
Remember to always consult the product label and any accompanying safety data sheets (SDS) for specific instructions and recommendations provided by the manufacturer.
Q. If the recent outbreak of the Langya Virus in China spreads, will Bacoban for Aerospace be effective against it or will it help to reduce its spread?
A. First we had Covid, now we have Monkeypox, next may be Langya henipavirus (LayV) as it is a new Zoonotic type of virus which is the same type as Covid and has so far infected dozens of people in Chuzhou in the eastern part of China. Zoonotic type of viruses are relatively easy to destroy when out of the body. Using Bacoban for Aerospace inside your aircraft will certainly reduce the risks of contamination by touch in the confined spaces of the aircraft cabin, various high risk touch points such as lavatories, door handles, galleys, rest rooms, overhead lockers etc. Bacoban for Aerospace is effective against all Zoonotic types of viruses.

Q. Is there a cleaning product for using as a tech wash inside aircraft wheel wells which cleans and degreases oil, hydrolic oil and corrosion inhibiting compounds for example dinitrol?
A. Yes, we have a solvent free non flammable product Lotoxane HD which is ideal for this purpose.
Q. What does log reduction mean when you talk about disinfectant effectiveness?
A. Companies and standards use log reductions to prove efficacy of products against a variety of bacteria, fungi and viruses. It is vital that the log reductions reduce the contaminated area to below 10 particles to ensure protection. While levels of bacteria and viruses vary depending upon locations, regularity of cleaning and surface type, sneezing and coughing releases hundreds of thousands of particles and contaminated areas can carry millions of microbes. A product can kill to:
– 3-log reducing 10,000 particles to 10 but anything above that level leaves a potential for infection
– 4-log reducing 100,000 particles to 10
– 5-log reducing 1,000,000 particles to 10
– 6-log reducing 10,000,000 particles to 10
Typically, a minimum of 5 log is required to ensure that contaminated areas can be disinfected. Speed of effectiveness and conditions are less important than the kill rate itself as these can be dealt with on site. Nothing is more important than effective kill.
Q. During the winter months, there is a build up of aircraft deicing fluid / glycerine which appears as a thick sticky substance which builds up on horrizontal surfaces of the aircraft mainly. Is there a product which will easily remove these deposits?
A. Our Aerowash is very good at softening and removing deicing fluid residue. We recoment spraying a liberal amount onto the surface, allow to soak before agitating with one of our scrub pads. This will redissolve the fluid allowing it to be easily wiped away.
Q. Is Bacoban for Aerospace effective if applied to soft furnishings or fabrics?
A. Yes, Bacoban for Aerospace has been tested in a laboratory according to EN ISO 20743:2021 and found to have an activity of log 3+, strong anti bacterial properties. The test certificate can be downloaded HERE.
Q. What is the best product to use to clean my aircraft?
A. The answer to this will depend on a few required outcomes. A cleaner or degreaser will remove any dirt, skydrol, dust or oil on the aircraft, this is often the first stage when cleaning an aircraft underbelly, under wings etc as these areas are usually the worst due to landing / take off when water is thrown up carrying dirt etc onto these areas. Once clean, it is often the case that a cleaner with a polymer or wax is use all over the aircraft. With the polymenrs / waxes, the surface is left with some additional protection. This can be an easy clean surface, added UV protection etc. Most importantly is that these paroducts will leave the surface smooth redusing drag. When drag is reduced, fuel consumption is reduced – fact!
Q. I have seen adverts for Bacoban WB which is a concentrate and cheaper than Bacoban DL. Can I use Bacoban WB to disinfect or clean the inside surfaces of my aircraft?
A. No, Bacoban WB has a very short shelf life once mixed with water and must be used withing an hour. It was developed for use in industrial / agricultural settings where extremely large areas are treated, slightly different grades of the ingredients were used to reduce the cost. Using Bacoban WB inside an aircraft will most likely cause discolouration of some types of surfaces. Alway use Bacoban DL inside aircraft, this will ensure that no surfaces are discoloured and operators working in the aircraft do not use product which has passed its shelf life.
Q. Is there a product or tyre dressing which I can use to make my aircraft tyres look new and shiny?
A. No, tyre manufacturers recomend using soap and water only for cleaning, the silicones used in dressings will dry the rubber of the tyre which accelerates cracking and possible pressure leakage. Here is an extract from the Goodyear Tyre maintenance manual.
Protecting Tires From Chemicals and Exposure
Tires should be kept clean and free of contaminants such as oil, hydraulic fluids, grease, tar, and degreasing agents which have a deteriorating effect on rubber. Contaminants should be wiped off with denatured alcohol, then the tire should be washed immediately with soap and water and inspected for surface damage such as blistering or softening. When aircraft are serviced, tires should be covered with a waterproof barrier. Tire coatings or dressings: Goodyear adds antioxidants and antiozonants to the sidewall and tread to help prevent premature cracking from ozone and weather exposure. There are many products on the market that are advertised to clean tires and to improve appearance and shine. Since many of these may remove the antioxidants and antiozonants, we do not endorse any of them unless the tires are to be used for display purposes only. Aircraft tires, like other rubber products, are affected to some degree by sunlight and extremes of weather. While weather-checking does not impair performance, it can be reduced by protective covers. These covers (ideally with light color or aluminized surface to reflect sunlight) should be placed over tires when an aircraft is tied down outside. Store tires away from fluorescent lights, electric motors, battery chargers, electric welding equipment and electric generators, since they create ozone which can have a deteriorating effect on rubber.

Q. Do you have a ‘Teflon’ coating for applying onto my aircraft paint? I am told it makes the aircraft easy to clean, reduces drag and fuel consumption and varius other advantages.
A. No, It is physically impossible to coat an aircraft with Teflon. Teflon has to be melted on to the substrate (eg frying pan) at 700 degrees centigrage, it then cools down and adheres to the sand blasted surface. Bear in mind that not much sticks to teflon, so how does Teflon stick to paint! Here is an exert from DuPont, the manufacturer of Teflon and the company that invented it:
Although Teflon® is an exceptional product when used as intended; it provides no benefit in a wax or polish. According to G.R. Ansul of DuPont’s Car Care Products, Specialty Products Division, “The addition of a Teflon® flouropolymer resin does nothing to enhance the properties of a car wax. We have no data that indicates the use of Teflon® fluoropolymer resins is beneficial in car waxes, and we have not seen data from other people that support this position.” Manufacturers of gimmick and over-hyped products sometimes claim that their products contain Teflon®, hoping that the consumer will believe there is something special about that product. Ansul also notes that, “Unless Teflon® is applied at 700 degrees F, and using a dissolving chemical C8, it is not a viable ingredient, and is 100 percent useless in protecting the paint’s finish.” This is hot enough that your car’s paint (let alone your car) wouldn’t survive. Information resource- Grisanti, Stephen “The Truth About Teflon®”
One other very important point to remember is that Teflon is banned in many countries but only in the making of cookware. And its primary component, PFOA, has been wholly removed from cookware since 2013. Both DuPont and 3M knew about the harmful effects of using PFOA in Teflon production, but they still used it. After knowing that chemicals of Teflon are not safe for human health, many countries have banned the use of chemicals like C8 in the production of Teflon. With the UK being one of the leading countries to ban it in 2005. Other countries, such as the United States, also banned it in 2014.
Teflon might be banned from these countries, but it is still produced to this day and is still used in making some other materials such as wires, clothing, etc
Q. Do any of the aircraft cleaning or polishing products sold by Frasers Aerospace contain Silicone?
A. The simple answer is no. Silicone, or more specifically ‘free silicone’ is a major concern for all industries including aerospace as it createsissues with adhesion and apperarance when applying coats of paint onto the surface. A typical problem faced in aviation is ‘rivet pop’ where contaminants ingress into the hole where rivets are. This caused delamination issues resulting in the applied paint ‘popping off’. Other issues which can be caused are ‘pinholes’ and ‘fisheye’ defects in the paint.
Q. Can disinfectants not listed on the US EPA List N be used on aircraft or other surfaces like hospitals, homes, trains busses etc?
A. Yes, the US EPA approval is only applicable to disinfectants sold in the USA, it does not apply to the UK or European countries. Typically, an EPA approval can take 2 years or more to achieve and will cost many millions of dollars. In reality, when virus outbreaks occur, the EPA approval process can be a hinderance.
Q. Which Aircraft manufacturers have approved Bacoban for use onboard their aircraft?
A. Most of the major aircraft or airframe manufacturers have approved Bacoban now, namely Boeing, Airbus, Dassault Falcon, Bombardier, Textron and Embraer. More may have approved the use by now.
Q. Is Bacoban for Aerospace effective against Monkeypox virus infection?
A. Human monkeypox or MPX, is a zoonotic type viral disease caused by the Monkeypox virus MPXV. The visual presentation is similar to that of the well known smallpox. The human monkeypox caused outbreaks in the tropical rainforest regions of Central and West Africa. It is not seen as a notifiable disease at the EU/EEA level.
The identification in May 2022 of clusters of monkeypox cases in several non-endemic countries with no direct travel links to an endemic area is atypical. Further investigations are underway to determine the likely source of infection and limit further onward spread. As the source of this outbreak is being investigated, it is important to look at all possible modes of transmission in order to safeguard public health.
Monkeypox virus is an enveloped virus that has an outer envelope. It belongs to the Orthopoxvirus genus of the Poxviridae family. The Orthopoxvirus genus also includes Cowpox virus, Vaccinia virus, Variola virus and several other animal-related, types.
The ability of a disinfectant to kill COVID-19 virus is related to the chemical make-up of both the virus and the disinfectant. Disinfectants work by chemically inactivating viruses. The lipid envelope that surrounds the monkeypox virus and all other enveloped viruses is easily attacked or disrupted by the disinfectant and this occurs regardless of the structure of the proteins on the surface of the viruses. The general mode of action of how a disinfectant attacks an enveloped virus is well known.
Monkeypox is transmitted to humans through contact with an infected animal or human, or with material contaminated with the virus. The virus enters the body through broken skin, the respiratory tract or the mucous membranes. The incubation period is typically around 10 days, but can range from 5 to 21 days.
The principal mode of transmission is thought to be direct contact with MPX lesions or with the patient’s belongings that have been in contact with the lesions. Therefore, caregivers and relatives should avoid touching skin lesions with bare hands, wear disposable gloves or similar ppe, and observe strict hand hygiene and washing. It is also reported that human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person or recently contaminated objects. The importance of hand hygiene by using soap and water or alcohol-based sanitizer should be emphasized.
Contaminated surfaces should be cleaned and disinfected. Standard household cleaning/disinfectants may be used in accordance with the manufacturer’s instructions.
Dishes and other eating utensils should not be shared. It is not necessary for the infected person to use separate utensils if properly washed. Soiled dishes and eating utensils should be washed in a dishwasher or by hand with warm water and soap.
Hand hygiene (i.e., hand washing with soap and water or use of an alcohol-based hand rub) should be performed by infected persons and household contacts after touching lesion material, clothing, linens, or environmental surfaces that may have had contact with lesion material.
Laundry (e.g., bedding, towels, clothing) may be washed in a standard washing machine with warm water and detergent; bleach may be added but is not necessary. Care should be used when handling soiled laundry to avoid direct contact with contaminated material. Soiled laundry should not be shaken or otherwise handled in a manner that may disperse infectious particles.
You can continue to use Bacoban for Aerospace with full confidence against the transmission of the Monkeypox virus, Bacoban for Aerospace has been tested and found effective against enveloped types of viruses.
Q. Is Bacoban effective against the Marburg Virus?
A. The Marburg Virus, closely related to Ebola. This has currently been only in Ghana and is typically passes from fruit bats to humans. The WHO is keeping an eye on this virus that has a death rate between 23-90% of affected people. Viruses have certainly been on everyone’s mind from COVID-19, monkeypox and now Marburg. As the Marburg virus is classed as an enveloped virus, Bacoban is effective in destroying it when outside the body on surfaces.
Q. Passengers have reported bed bugs onboard aircraft, is there an approved chemical which can kill them?
A. Yes, Bacoban for Aerospace has been tested and is effective for up to 72 hours against bedbugs. Contact us for more information to help protect passengers from viruses, bacteria, bedbugs and a whole lot more!
Q. Where is Bacoban made?
A. Bacoban is manufactured (and patented) by Ropimex in Germany.
Q. Do you have a product which will clean and deodorise galley and lavatory areas?
A. Nuvite Rid (Galley and lavatory surface cleaner/deodoriser) – Used for cleaning and deodorising galley surfaces and lavatory areas – metal, laminates and plastics. Supplied as concentrate – dilute 1:10 parts water for use.
Q. Which cleaning product do you recoment to use for cleaning internal hard surfaces of an aircraft including restrooms?
A. Nuvite C-49 (General use cleaner) – Used for cleaning all types of surfaces generally found in aircraft cabins: effective and safe for cleaning carpet, fabrics, plastics, leather, vinyls, metals and laminates. Supplied in concentrate – dilute 1:8 with water, or dilution can be varied for spotting needs without safety problems for user or materials.
Q. Can aircraft fuel savings be made by reducing perastaltic drag or keeping an aircraft clean?
A. Airlines advocate using a variety of measures to improve aircraft fuel efficiency. One of the engine adjustments that can be made on non-FADEC powerplants is a variable stator vane optimum rig, which can reduce engine fuel consumption up to 0.5 percent. Airlines also “dry wash” some airplanes, which involves applying a special polishing powder to the exterior rather than washing it. It is believed that the smoothness of the dry wash finish has a positive influence on fuel consumption. Mickey Cohen, vice president of operations and engineering for AAR, said that his people always are on the lookout for maintenance issues that could affect fuel consumption. “We tell our inspectors to pay particular attention to misalignment of body panels, doors and closure panels. If a door is inset up to a quarter inch, it could function properly and there would be no airworthiness issues, but it would cause additional fuel burn because of additional drag.” Cohen said that jetliners tend to gain up to 150 pounds of weight because of accumulating moisture, dust and dirt. He suggested that operators periodically clean out the wheel wells and other nooks and crannies of airplanes. “With fuel at the price that it’s at, you look at everything you can,” he said. Achieving optimum fuel savings requires cooperation between aircraft manufacturers, airlines and MRO providers, but the efforts clearly are worthwhile. “A lot of these programs seem small,” said American’s Chealander. “But when you add them up, you can save millions of gallons [of fuel] just by being conscientious about the little things.” In 2005, American saved 84 million gallons, and this year the carrier expects to save close to 100 million. At more than $2 a gallon, those are impressive savings.
Q. What is the difference between wet wash and dry wash?
A. The two basic types of exterior wash services are Wet Wash and Dry Wash (Rinseless). Often the Dry Wash process is referred to as a Wax process. Conversely, the chemicals used in Nuvite Drywash (NuPower) programs will not form the build-up associated with wax based agents. Additionally, the Nuvite Drywash agents will not create the static concerns of a teflon treatment or the repaint concerns of a silicone based polish.
Dry Washing is accomplished by applying the drywash compound on the aircraft surfaces (both painted and bare metal) and agitating for removal the soils as outlined in the General Cleaning procedures outlined below. This process is designed to lift the soils, oxidation and stains from the surface. After the drywash agent is applied and agitated, it is then either hand or machine buffed from the surface. This buffing or detailing action completes the deposition of the polish and protective agents onto the surface. Resultingly, enhancing the gloss factor while protecting the paint coating.
The Dry Wash Process is performed for six basic reasons:
1.Removal of oxidation and other stains that normal wet or waterless washing does not remove.
2. A protective coating is left on the paint surface that will retard oxidation, weather wear and re-deposition of soils.
3. Environmental concerns are relaxed where Wet Wash rinsing is prohibited.
4. Does not interfere with maintenance functions that are in process.
5. An aerodynamically clean surface creates less drag and increases fuel efficiency
6. An aircraft whose appearance is more appealing to eye of the consumer, promotes confidence in the professionalism of his chosen airline.
Q. Are any of your chemical products Nano or Nanotech?
A. All of our products are technically Nano or Nanotech. The term ‘Nano’ means that the particle size is measured in Nanometers. All of our cleaners, and cleaner polish products fall into this catagory. Unfortunately many companies are misusing the term ‘Nano’ to make claims about their products which may not be true or relevant. It is unfortunately a marketing ploy to get customers to believe that their product is something special or different to other suppliers.
Q. Is it O.K. to dilute the any of the Nuvite dry wash products for aircraft cleaning with water?
A. Standard routine procedures do not recommend the dilution of the NuPower II, NuPol for the following reasons:
- The effectiveness of the Ultra Violet protection barrier could be reduced significantly.
- The ability to directly clean the more complex soils and stains will be adversely affected.
- Drying time required for the protective barrier to satisfactorily adhere to the painted surface of the aircraft will also be increased.
Note: However, it is acknowledged that during extremely hot and dry weather the elevated aircraft skin temperature &/or air temperature will drastically reduce the time involved in drying phase. Which may create adverse conditions for the cleaning phase by not permitting enough time for effective surface soil agitation. Hence a dilution ratio of 4/1 (Nuvite drywash to water) will affectively lengthen the cleaning time to permit proper agitation of the surface before the drying phase begins.
If the drying phase begins, it may interfere with the effectiveness of cleaning the surface for proper and uniform deposition of the protective barrier. It is better to maintain a wet surface till all cleaning agitation is accomplished. A wet working surface is simply maintained by additional application of drywash product.
Q. Is it possible to avoid the powdery haze that develops during the drying phase? Sometimes while removing the dried residual haze a light deposit of dust is noted on lower surfaces, or occasionally noticed as an airborne particulate. Is this dust a safety hazard through inhalation or exposure?
A. The drying (hazing) phase in any quality drywash process is critical for proper deposition and the chemical attachment of the polish/UltraViolet protection component to the painted surface. Agitation of the surface, while the formula is wet, is used to free and encapsulate soils to control safe removal with the resulting haze. A dust build up or particulate settling during removal of the residual haze is a result of excessive chemical application and/or improper procedural practice. Excessive application of drywash chemicals may be the result of the misguided perception that if “a little amount of chemical is cleaning good a greater amount of chemical will clean faster and easier”!! The Nuvite drywash formulas are designed to clean specific volumes of soil with specific amounts of chemicals. It is best to remember that more chemical can be added when and if needed. If an excessive amount of drywash chemical is used to clean a small soiled surface area – the result will be a thick build up of unused, wasted drywash material. Improper procedural steps will create the same build up effect, resulting in an inefficient, unnecessary amount of dried residual haze. As the Nuvite training steps advise, surface agitation should be finished by feathering or thinning the surface of excess wet chemical to the next overlapping, adjoining area to be cleaned. Thus leaving behind, only a thin effective film of polish/UV protectorant to affectively attach to the underlying (cleaned and prepped) paint surface. The potential for airborne dust particles being the result of an excessive layer of residual haze. Proper procedures will have the mopheads capturing and containing surface soils encapsulated within the residual haze being removed. Routine changing of mopheads will reduce surplus build up that can result in free dust particles. NOTE: Mopheads should never be unloaded of residual haze by banging them on the stands or manlifts!!
Q. Who makes Bacoban?
A. Bacoban is manufactured by Ropimex based in Neunkirchen DE. Ropimex hold the EU patent for Bacoban. Ropimex hold the patent for Bacoban. Frasers Aerospace has been approved by Ropimex to fill and bottle Bacoban for Aerospace in the UK.
Q. I have been using Autosmart G101 for many years and believe it is the best cleaner on the market, to you have an equivalent?
A. Our Tek Wash performs exactly the same, it is very difficult to see the difference between the products.
Q. What is the effect of the Nuvite drywash cleaners on Seals? Composites? Acrylics? Radomes?
A. All Nuvite drywash products conforms to OEM specifications, namely the Boeing D6-17487, McDonnell-Douglas CSD-1, Airbus NTO and SAE AMS-1650 for safety to acrylics, plastics, paint, metal, etc.. NuPower II is approved for direct in-house use by Boeing, McDonnell-Douglas (now Boeing), Airbus, Bombardier, Raytheon, etc. Regarding the question about the specific affect of Nuvite drywash products on radomes, the product line in the Nuvite Drywash program is based directly on the NuPower II formulation. Since the introductory approvals, in 1980, NuPower II has been utilized by major airlines and aerospace clients without health, environmental or structural incident. To the best of our knowledge, no masking or protective action of radomes(or seals) against exposure to any of the Nuvite Drywash products has ever been required or even proven necessary. Nuvite continually forwards samples of all significant Nuvite product lines, as requested, to Boeing Materials Technology(BMT) and Scientific Material International(SMI), for updated testing and concurrence for conformance to all aircraft structural and surface certification requirements.
Q. What are the affects and/or added complications if moisture or high humidity is present? Can the excessive condensation that develops on a parked aircraft be overcome, and does it interfere with the deposition of the polish/UV protection agent?
A. The affects of moisture are varying to any process associated with Drywash (waterless cleaning) process.
Fog: A high concentration of humidity in the air will obviously retard the ability of any wet material to dry, hence increasing the amount of time for a drywash chemical to haze. A simple increase of the area size being cleaned will allow extended drying time. It is advised in Nuvite cleaning procedures that areas as large as forward of the wing be cleaned at one time before back tracking with personnel and equipment for the removal phase.
Condensaton: Water collection on the crown of an overnight aircraft presents the largest problem to a drywash cleaning task. The parameters that must be evaluated involve the amount of moisture, atmospheric air movement and surface soil conditions. Moisture can be dealt with by:
Excess moisture may be handled through a simple wipe down to reduce the amount of water prior to drywash application, being sure to start at the top working down. Moving onto new zones before moisture reforms that will require further removal.
Relative amounts of moisture can be absorbed into the drywash chemical during the application phase but the surface will require a longer drying phase (as outlined in hot weather applications in question 5 below). Light soil cleaning performance is unaffected by dilution of Nuvite drywash formulas.
Direct application of drywash chemical can be applied to wet surfaces, agitated, then followed by a quick dry mophead wipe removal of saturated chemical on the surface. Then allowing time to dry and remove residual haze as per normal procedures.
Q. Is Bacoban effective against the spread of Monkeypox?
A. The Monkeypox virus is classed as an enveloped virus. Bacoban (ingredients Benzalkonium chloride) has been proved effective in destroying all forms of this type of virus.
Q. Can Bacoban be used in kitchens and food preparation areas?
A. Bacoban is safe to use in food preparation areas like kitchens etc. THe laboratort test certificate can be provided upon request.
Q. How important is it to use approved chemicals to clean aircraft?
A. Approved chemicals have been tested by an accredited laboratory on various aircraft substrates to ensure that no damage or corrosion is caused on an aircraft. Typical car care products contain chemicals like ammonia and sodium hydroxide to boost the cleaning power of the product. These chemicals do no harm to cars etc, however they are both very corrosive to aluminium. Corrosion on aircraft can cause an aircraft to crash resulting in possible fatalities.
Q. Your website says that Bacoban for Aerospace lasts for us to 10 days on surfaces. Why is this important?
A. If you use a standard disinfectant to disinfect a surface, any traces of viruses and bacteria will be destroyed. The problem is that after 10 minutes, someone with a virus can contaminate the surface, the next person to come along and touch this surface will run the risk of becoming contaminated. If Bacoban for Aerospace was used to clean and disinfect this surface initially, the initial contamination would not occur as the residual effect of the Bacoban for Aerospace will destroy the virus or bacteria therefore preventing the spread. Although Bacoban for Aerospace will protect surfaces for up to 10 days, we recommend regular cleaning and re-application as the product can be removed.
Q. What is the difference between Bacoban DL and Bacoban WB?
A. Bacoban WB is used as an economical product to mix (supplied as a concentrate) and use to disinfect surfaces. The problem with this version is that it HAS to be used the same day, it CANNOT be kept overnight to be used the next day. It does not remain stable for longer periods. Bacoban WB is not used inside aircraft as some staining and discolouration has been known to have occured on sensitive surfaces. Bacoban DL on the other hand is supplied ready to use, it has a 2 year shelf life when mixed, it does not discolour or stain sensitive surfaces. Bacoban DL is the ONLY type of Bacoban that should be used inside an aircraft. Other suppliers (who do not have aviation knowledge) will suggest Bacoban WB, if you choose to use this version, it is at your risk.
Q. Is Bacoban patented?
A. Yes, Bacoban has been patented by the manufacturer Ropimex.
Q. There are 7 grades of NuShine on your website. Which Grade do I use?
A. Fortunately, NuShine ll’s graded system of metal polishing compounds tackles a variety of surface conditions, from heavily corroded to lightly oxidized, and on to that final, mirror-finish shine. Where you begin depends on the severity of your metal problem. For example… let’s follow the system using NuShine IIF7 for metal surfaces discolored by heavy oxidation, some corrosive pitting, and in need of scratch repair. NuShine II compounds burnish metal through a synergetic chemical/mechanical process where NuShine IIF7’s powerful abrasive formula is actioned using a circular/rotary buffer. Following the process in repetition via NUVITE’s recommended SHOULDER ZONE polishing technique, blends the edges of the corrosive pitting with the shallow angle of pit walls and scratches. With a level metal surface moisture and foreign material that perpetuate corrosion are locked out. The next polishing step calls for NuShine IIC for oxidation removal and repolish. Applied and worked similarly to NuShine IIF7, NuShine IIC will eliminate the remaining very small pits that trap black polish residue and prepare the surface for final finish with NuShine IIS, which is the key to that showroom, mirror-image shine.
Q. Is there a specific procedure to follow when polishing aluminium?
A. No, there is no specific procedure to follow as such. The reason is that there will be different degrees of oxidation present on the aluminium. The level of oxidation on the leading edges, intakes or even if polishing Airstream Caravans will be different all the time. The degree of oxidation will dictate which product (Nuvite NuShine) to begin with. Coursed grit particles will remove deeper more extensive corrosion on the aluminium. The finer grades will reduce the swirl marks which will eventually result in the mirror finish. We have a large collection of instructional videos, downloadable guides on our website to assist you with your polishing process.
Q. On your website you have two types of aircraft cleaner listed. A cleaner / degreaser and a cleaner / polish. Whats the difference?
A. A cleaner / degreaser will clean and degrease the aircraft fuselage removing insects, oil, skydrol, pollutants, dust etc etc as you would expect from any cleaning compound. The Cleaner /polish will do the same cleaning, however it will leave behind either a wax or a polymer protective layer on the painted surface. This layer offers a number of benefits, the layer is sacrificial and will reduce damage by harmful rays from the sun which will fade paint, the surface will take longer to become dirty again and most importantly, the surface of the paint will become smoother which reduced drag and improves the fuel efficiency of the aircraft.
Q. What are the things that we should avoid when cleaning an aircraft?
A. Quite simply, non-approved cleaning products. Different chemicals have different approvals depending on which part of the aircraft is being cleaned, ensure you use the correct chemical for the application. Additionally to this, do not clean pitot tubes, static wicks, angle of attack sensors etc. These should be kept clean by the engineers. Many years ago there was an incident where aircraft cleaners masked the holes of one of the sensors, after cleaning the tape was not removed. The instruments ended up displaying incorrect information to the pilots which resulted in the aircraft crashing. Another area be aware of are the aircraft brakes. Never spray anything into them, if hot they can crack, if cold the chemical can remain there and freeze during flight. When landing tires can be blown again resulting in an accident.
Q. What is the importance of cleaning the aircraft internally and externally?
A. As the aircraft cabin is relatively small and cramped, viruses and bacteria will be carried on board by passengers all the time. Food and drink is consumed at the seat, multiple people use a number of limited rest room facilities. All these factors are not ideal for passengers health, it is the duty of care of airlines to ensure that passengers well being is a priority. It is important to maintain a clean exterior of the aircraft to ensure that maintenance can be carried out effectively, dirt and contaminants can cause damage to the aircraft, clean aerodynamic fuselage surfaces have shown that fuel savings can be made, and importantly it is the airline image, a clean shiny aircraft will appear to be safer than a dirty grubby aircraft.
Q. I have been using Simple Green to clean my aircraft, you have a more cost effective equivalent?
A. Our Tek Wash performs exactly the same, it is very difficult to see the difference between the products.
Q. What is aircraft dry wash?
A. Technically, a ‘Dry Wash’ is where the cleaning chemical is applied by various means, the surface is agitated and then the chemical with the dirt is manually removed with a cloth. Nothing lands onto the airport apron or goes into the storm water drain causing pollution. A ‘Wet Wash’ is similar, except that the chemicals and dirt are washed off the fuselage with a hose pipe of high pressure wash onto the airport apron. They then run off into storm water drains causing pollution. With the current environmental issues, Dry Washing will save many thousands of litres of water per aircraft. This runs into thousants of tons of water wasted per year! Traditional wet wash can consume 8000 litres of water per aircraft. With a Dry Wash, this is reduced to only a few litres.
Q. Do you supply a ‘Teflon’ coating for aircraft?
A. The short answer is ‘No’. Physically, it is impossible to apply Teflon or PTFE onto a painted surface. If nothing sticks to Teflon, how can it stick to paint is the logical thought process. Manufacturers can add micronised Teflon into ther wax polish, the wax will hold the Teflon in place on the aircraft paint. The problem is that the longevity of this will rely totally on the quality of the wax used. Here is an excerpt from an article which may add more light to this subject:
A. Each 100 g of solution containins: Benzalkonium chloride 0,26 g, sodium pyrithione 0,025 g, polycondensates, perfume substances, purified water. Ingredients according to regulation (EC) No 648/2004: less than 5 % cationic surfactants, disinfectants, perfumes.
Q. Can Bacoban be used inside hospitals and medical surgeries?
A. Some of the first users of Bacoban were hospitals in Germany as Bacoban was developed for hospitals in mind. The natural progression for Bacoban being used in hospitals was to use it in surgeries, Doctors consulting rooms, waiting rooms etc. Anywhere additional long term protection is seen as a benefit to protect patients.
Q. How often should you clean an aircraft?
A. This will depend on the hours flown by the aircraft. Regular cleaning will always be a benefit, keeping the aircraft looking new will help with maintenance, fuel efficiency and longer term resale value.
Q. Can I use Windex on my Aircraft’s windows?
A. No. Windex contains ammonia which is corrosive to aluminium which is the main metal used to manufacture aircraft. Only approved products must be used. Aircraft cockpit windows have a special coating called ‘Rain-ex’ which is a hydrophobic coating repelling water during flight through rain as due to the airspeed, wipers if present, cannot be used.
Q. How long is the Bacoban cleaner effective for on surfaces?
A. Bacoban remains active for 10 days on a hard surface provided it is not physically removed. It is effective on fabrics for a year, again provided that it is not removed. Bacoban is tested to an internationally accepted standard test method ASTM E 2180.
Q. Does Bacoban offer protection against Covid?
A. Yes, Bacoban has been tested and is effective against all encapsulated virus types, additionally, the active ingredient which is a Quaternary ammonium compound benzyl-C12-16-alkyldimethyl is listed by the WHO and EASA as effective against Covid and numerous other viruses (including EBOLA, H5N1, H1N1, Rotaviruses and many more)
Q. What is Bacoban disinfectant?
A. Bacoban is a patented disinfectant against viruses and bacteria, it remains active on hard surfaces for 10 days or more provided it is not removed. Bacoban is extensively approved and used across the aviation industry.
Q. Where is Bacoban for Aerospace manufactured or who makes Bacoban?
A. Frasers Aerospace manufacture Bacoban for Aerospace in the United Kingdom. The primary ingrediant for Bacoban is manufactured in Germany by Ropimex.
Q. How do you use Bacoban?
A. Heavily soiled areas or surfaces must be pre-cleaned with a suitable degreaser of cleaner. Ensure that the surface is fairly dry after cleaning. Bacoban can then simply be sprayed onto the surface and wiped with a clean cloth or microfiber. Do not wipe totally dry.
Q. How do you fog with Bacoban?
A. Select a suitable fogging / nebulising machine. Different machines will be used in different ways. There is one point however which is important, the optimum droplet size which must be between 20 and 30 microns. The finer
the droplets, the better the coverage is. Personal protective equipment (PPE), follow the instructions on product labels. Ask your safety-clothing supplier to help you get the right PPE. Respiratory protective equipment
(RPE) is needed. Make sure respirators have an Assigned Protection Factor (APF) of 10 or more, and are CE marked. Seek advice from your RPE supplier. Replace RPE filters as recommended by the supplier. Throw away disposable RPE after one use. Make sure you know how to check that RPE fits correctly. Keep RPE on until you have left the work area. Wear protective gloves – single-use nitrile gloves are acceptable. If you must use latex
gloves, use only ‘low-protein, powder-free’ gloves. Throw away single-use gloves every time you take them off. Use protective goggles to protect eyes. Wear a hooded coverall – cotton or porous polypropylene is probably the best material. Skin creams are important for skin protection and help in washing contamination from the skin. These are not ‘barrier creams’. After work creams help to replace skin oils.
Q. Do you have a degreaser equivalent to Granitize XE3?
A. Our Tek Wash is the same technology as used in XE3, for more information visit our website here.
Q. Is there an easy way to remove insects and bugs from leading edges post flight and brighten the surface?
A. Yes, simply use our Nuvite NuImage. Use “as is” (do not dilute) to a terry cloth towel. Dried bugs can be safely loosened by allowing them to liquefy before rubbing. Keep surface wet with material until bugs are removed. When fully dry, clean with a cotton towel or flannel cloth on polished metal.
Q. What is the difference between Granitize AECI 3 X20-18 and Granitize AECI 3 X20-15?
A. Granitize AECI 3 X20-18 is used to apply to polished aircraft aluminium surfaces to delay oxidation on leading edges, inlets and tail surfaces. Granitize AECI 3 X20-15 is the same product, with a slightly adjusted solid content and it is applied to painted surfaces.
Q. Do you have an insecticide to disincect an aircraft to kill bed bugs?
A. Yes, our Bacoban for Aerospace has been tested with live bedbugs and showed good efficacy on non-porous glazed tiles against Bed bugs, Cimex lectularius, when tested fresh, with on average 100 % mortality after 24 hours. The efficacy decreased after 10 days of ageing with on average 33 % mortality after 24 hours, 60 % after 48 hours and 87 % after 72 hours. For more information, look through the test report HERE.
Q. Does the cleanliness of an aircraft fuselage affect the fuel efficiency?
A. The cleanliness of an aircraft fuselage can indeed affect its fuel efficiency. When an aircraft is in flight, it encounters resistance from the air, known as drag. Drag can be classified into two main types: parasite drag and induced drag. Parasite drag is caused by factors such as air friction and form drag. Air friction occurs when the air molecules rub against the aircraft’s surface, and form drag is caused by the shape of the aircraft. A clean and smooth fuselage reduces parasite drag by minimizing air friction and optimizing the aerodynamic profile of the aircraft. Any dirt, grime, or roughness on the fuselage surface can disrupt the smooth flow of air over the aircraft, leading to increased parasite drag. This increased drag results in higher fuel consumption as the engines have to work harder to overcome the resistance. Studies have shown that a dirty aircraft can experience a significant increase in fuel consumption compared to a clean one. Furthermore, the accumulation of dirt and contaminants on the fuselage can also impact the performance of the wing surfaces, particularly the wings’ leading edges. These areas are critical for lift generation. Contaminants can disrupt the smooth flow of air over the wings, leading to reduced lift and increased drag, further decreasing fuel efficiency. Airlines are aware of the impact of fuselage cleanliness on fuel efficiency and, therefore, invest significant effort in keeping their aircraft clean. Regular washing and maintenance procedures are carried out to remove dirt, grime, and contaminants from the fuselage surfaces, ensuring optimal aerodynamic performance and fuel efficiency.
