AIRCRAFT FINISH CARE (CLEANING).
EXTERIOR SURFACES.
The airplane should be washed with a mild soap and water, harsh abrasives or detergents used on painted or
plastic surfaces could make scratches or cause corrosion of metal surfaces. Cover areas where cleaning solution
could cause damage. To wash the airplane, the following procedure may be used:
1. Flush away loose dirt with water.
2. Apply cleaning solution with a rag, sponge or soft bristle brush.
3. To remove stubborn oil and grease, use a cloth dampened with naphtha.
4. Where exhaust stains exist, allow solution to remain on the surface longer.
5. Any good automotive wax may be used to preserve the painted surfaces. Soft cleaning cloths or a
chamois should be used to prevent scratches when cleaning or polishing. A heavier coating of wax on
the leading surfaces will reduce the abrasion problems in these areas.
WINDSHIELD AND WINDOWS.
1. Remove dirt, mud, etc., from exterior surfaces with clean water.
2. Wash with mild soap and warm water or an aircraft plastic cleaner using a soft cloth or sponge and a
straight rubbing motion. Do not rub surfaces harshly.
3. Remove oil and grease with a cloth moistened with kerosene.
— Note —
Do not use gasoline, alcohol, benzene, carbon tetrachloride, thinner, acetone or
window cleaning sprays.
4. After cleaning plastic surfaces, apply a thin coat of hard polishing wax. Rub lightly with a soft cloth.
Do not use a circular motion.
5. A severe scratch or mar in plastic can be removed by using jeweler's rouge to rub out the scratch.
Smooth both sides and apply wax.
HEADLINER, SIDE PANELS AND SEATS.
1. Clean headliner, side panels, and seats with a stiff brush and vacuum where necessary.
— CAUTION —
SOLVENT CLEANERS REQUIRE ADEQUATE VENTILATION.
2. Soiled upholstery, except leather, may be cleaned by using an approved air drying type cleaner or foam
upholstery cleaner. Carefully follow the manufacturer‘s instructions. Avoid soaking or harsh rubbing.
3. Leather material should be cleaned with saddle soap or mild soap and water.
