Ensuring Safety and Compliance
Keeping an aircraft clean is essential for safety, operational efficiency and even passenger satisfaction. Proper cleaning procedures ensure that both the exterior and interior of an aircraft are free from contaminants, reducing wear and tear, improving aerodynamics and maintaining a hygienic environment for passengers and crew.
However, improper cleaning techniques or using the wrong products can lead to costly maintenance or environmental concerns.
This guide explores interior and exterior cleaning procedures and recommended cleaning products. Let us talk you through the best cleaning practices to ensure optimal maintenance and performance.
Exterior Cleaning Procedures
The exterior of an aircraft is exposed to harsh conditions during every flight. Regular cleaning prevents damage and ensures aerodynamic performance.
General Exterior Cleaning
Aircraft surfaces are exposed to oil streaks, dust and pollutants.
Common methods to remove these include:
Water and Soap Cleaning - Wet cleaning methods with products like Turco 5805 Liquid Soap - specifically designed to clean and brighten jet engine thrusts.
Degreasing Agents - Solvents such as Eurochem S.A. MIL-PRF-680 Type II High F.P. Degreasing Solvent remove oil, grease and fuel residues.
Glass Cleaning - Cockpit and passenger windows can be cleaned using GLYST A-1859 or Glasswax for enhanced clarity and safety.
Degreasing with Methyl Ethyl Ketone (MEK)
MEK is a powerful degreaser used for heavily contaminated surfaces. It dissolves grease, rust, dirt and other contaminants, although it must be handled with extreme care due to its flammability. Proper PPE and ventilation are necessary during application.
Engine and Turbine Cleaning
Engine components and turbines are subject to soot and contaminants. Cleaning methods must comply with MIL-PRF-85704 Type III specifications to ensure compatibility and avoid damage.
Interior Cleaning Procedures
Interior cleaning maintains hygiene, enhances passenger experience and supports crew safety. This involves cleaning surfaces such as carpets, seats, LCD screens, toilets and more.
Cabin Surfaces
Regular cleaning of cabin surfaces like seats and overhead compartments can reduce dust and stains.
Common solutions include:
Disinfectants like West Wecodyne Disinfectant for floors and carpets.
TT-N-95 Type II Solvents for screens and plastics.
LCD Screens
Cockpit and cabin touchscreens accumulate dust and fingerprints, reducing visibility and usability. Winsol APC-120-WX is effective for removing debris and maintaining screen clarity.
Toilet & Galley Areas
Products like AMS 1476B-compliant chemical deodorants and Chemetall Ardrox 1823 Super Blue Toilet Sanitizer ensure toilets and galleys remain sanitary, odor-free and safe for passengers and crew.
Factors to Consider When Selecting Cleaning Products
Material Compatibility
Ensure that the cleaning agents are formulated to match the surfaces being cleaned (e.g., metals, plastics or textiles).
Flammability
Some solvents, like MEK, are flammable. Use them with appropriate precautions and ensure adequate safety training and PPE.
Health and Environmental Safety
Choose biodegradable and eco-friendly cleaners to minimize environmental impact. Additionally, opt for non-toxic and non-harmful options for personnel safety.
Compliance with Aviation Standards
All cleaning agents must adhere to local aviation authority requirements and aircraft manufacturer specifications.
Best Practices for Aircraft Cleaning
To ensure optimal results, adhere to these best practices:
Follow Manufacturer and Regulatory Guidelines
Cleaning procedures must meet the standards set by the aircraft's manufacturer and aviation authorities.
Train Cleaning Personnel
Proper training reduces the risk of applying the wrong products or techniques, which can lead to damage or safety hazards.
Use Personal Protective Equipment (PPE)
Cleaning solvents can be hazardous. Cleaning personnel should always wear gloves, goggles and other necessary protective gear.
Adopt Environmentally Responsible Methods:
Choose biodegradable and eco-friendly products to minimize the environmental impact of cleaning activities.
Regular Maintenance
Scheduled cleaning, based on operational time or flight cycles, ensures that dirt and contaminants do not accumulate.
