AIRPLANE CLEANING INSTRUCTIONS
External Surfaces Cleaning Procedure
To wash the aircraft the following procedure may be used:
1. Flush out dirt
2. Apply cleaning solution with sponge or soft bristle brush
3. To remove stubborn oil and grease use a kerosene moist cloth
4. Where exhaust stains exist, allow solution to remain longer on the surface
5. Any good automotive wax may be used to preserve the painted surface.
Soft cleaning cloths or chamois leathers should be used to prevent scratches when cleaning or
polishing. A heavier coating of wax on the leading surfaces will reduce the abrasion problem
in these areas.
Avoid entry of solutions and flooding of soap into a/c openings such static
vents: it is recommended that openings and vents be plugged as a precaution.
Install protective caps if practical.
