Cabin Cleaning

Procedures

Cabin cleaning as a safety issue? Yes.

I've had a few flights where passengers were overcome by the fumes caused by cleaning solvents used by the ground crew the morning of, and once the night before a flight. What seemed innocent to the noses of those in the cabin at sea level pressure became so strong once pressurized, it caused difficulty breathing and noticeable blotches on the skin. We no longer allow any cleaning solvents on the aircraft.


 

Aircraft Cabin

[The Gulfstream Journal, June 27, 2014]

  • There are problems associated with using common household chemicals in the aircraft cabin, particularly in flight. Although common cleaners may be safe for the home, their use can be detrimental in aircraft. Many problems can occur, such as damage to the aircraft interior, components, or structure, but even more concerning is that using and/or mixing various chemicals can cause toxic fumes. In an enclosed cabin, this can have extremely dangerous effects and be a potential threat to the safety of the crew and passengers. Often, the mixing of chemicals is done accidentally when one towel or cleaning cloth has been used in one area with a particular cleaner, only to be later inadvertently used with a different cleaner/chemical, but the result can be a dangerous or possibly toxic mixture.
  • FAR 25,831 (b) states that "Crew and passenger compartment air must be free from harmful or hazardous concentrations of gases or vapors." In order to comply with this regulation, only safe chemicals should be used aboard the aircraft during flight.
    • Use only Gulfstream-recommended products for cleaning and maintaining the following surfaces: wood, vinyl laminate, plastic, plating, stainless steel, leather, vinyl, fabrics, carpet, and galley equipment such as sinks, ovens, microwaves, coffee units, and toilets.
    • Note: Manufacturers of commercial off-the-shelf equipment may not take into consideration that their units could be installed in an aircraft and used at altitude in a pressurized cabin. Therefore, manufacturer-recommended cleaners for this equipment may not be on the approved list for aircraft use.

      If your aircraft manufacturer doesn't include an approved list, the list shown here is for what Gulfstream has approved. Our cabin altitude rarely exceeds 6,000 feet so if we can't use a particular solvent, chances are you shouldn't either.

    • Use only clean, white, non-abrasive cotton rag toweling when cleaning fabric, leather, carpet, metal, plated or plastic areas, or any other surfaces.
    • or daily cleaning, use a clean, non-abrasive 100% cotton cloth with approved mild cleaners or detergents, followed by a clean, non-abrasive cotton cloth.
    • For in-flight use, use nothing stronger than a mild, non-abrasive liquid soap and water.
    • Chemicals containing chlorine or ammonia should not be used in flight or stored aboard the aircraft.
    • Do not mix ammonia and chlorine bleach. Some simple cleaners such as Windex® and Formula 409® contain ammonia or chlorine, as well as possibly other caustic chemicals. Often many cleaners contain these chemicals, but operators do not realize the cleaners can have detrimental effects.
    • Do not take chemicals such as regular chlorine bleach, ammonia, solvents, or various personal items such as nail polish remover aboard aircraft.
    • The old saying, "there is only so much you can do" applies here when it comes to passenger carry on articles. We certainly aren't going to interrogate every passenger for possession of nail polish remover. But, on the other hand, you are handed a case of the stuff for the luggage compartment, you should let the passenger know this stuff can be lethal at cabin altitudes if the containers were to break in flight and atomize into the air. In the Gulfstream the baggage compartment is aft and all air flow moves forward. If the passenger protests you can offer to have it sent FedEx. But I would, under no circumstances, allow a case of nail polish remover or similar solvents on the aircraft. (In the Air Force I was once given a direct order to carry a case of aircraft solvent on a Gulfstream. I refused, the general officer issuing the order went ballistic, the case was left on the tarmac, and nothing was ever said of the incident again. People can overreact at times, but once they figure out you are keeping things safe, they tend to calm down.

    • Never use full strength bleach on any carpet or fabric.
    • Aggressive cleaning of seat covering materials and carpet can remove the fire retardant.
    • Aerosol cans are not recommended for in-flight use, storage aboard the aircraft, or having in luggage.
    • To prevent possible damage to the aircraft interior, take care to not spill cleaning products in the aircraft.
    • Do not use a beater brush attachment when vacuuming fabric, leather, or any other materials.
    • Cleaning and maintenance of delicate fabrics should be done only by a trained professional using approved cleaners.
    • Do not allow spills to dry on fabric, carpet, or any other surfaces.
    • Do not use abrasives when cleaning plated or finished surfaces, plastics, or mirrors.
    • Do not use galley cleaning materials in other sections of the aircraft, unless approved for use in that area.
    • Do not intermix lavatory chemicals. Toxic fumes could result.
    • If the proper cleaning equipment, supplies, and procedures are not available, leave the cleaning task to a professional.

Avionics Displays

[Gulfstream Aircraft Outfitting Cleaning Manual, ¶1.]

  • Clean avionics displays only with approved cleaners, tools and Electronic Flight Instrument System (EFIS) X-405 Window Cleaner wipes. Immediately remove all dirt and spills. Do not allow spills to dry. Report stains that cannot be cleaned to maintenance.
  • Gently dust weekly with dashboard brush. Dust more frequently if required.
