CLEANING EXTERIOR SURFACES
The airplane should be washed with a mild soap and water. Harsh abrasive or alkaline soaps or
detergents used on painted or plastic surfaces couId 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:
t.
Flush away loose dirt with water.
Apply cleaning solution with a rag, sponge or soft bristle brush.
i.
To remove stubborn oil and grease, use a cloth dampened with naptha.
Where exhaust stains exist, allow solution to remain on the surface longer.
e.
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.
CLEANING WINDSHIELD AND WINDOWS
F.
Remove dirt, mud, etc., from exterior surface with clean water.
Wash with mild soap and warm water or an aircraft plastic cleaner. Use a soft cloth or sponge
using a straight rubbing motion. Do not harshly rub surfaces.
C. Remove oil and grease with a cloth moistened with kerosene.
NOTE
Do not use gasoline, alcohol, benezene, carbon tetrachloride,
thinner, acetone, or window cleaning sprays.
d. After cleaning plastic surfaces, apply a thin coat of hard polishing wax. Rub lightly with a soft
cloth. Do not use a circular motion.
e. 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.
