CHEROKEE CRUISER
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 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:
a.
Flush away loose dirt with water.
b.
Apply cleaning solution with a rag, sponge or soft bristle brush.
c.
To remove stubborn oil and grease, use a cloth dampened with naphtha.
d.
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
A certain amount of care is needed to keep the plexiglas windows clean and
unmarred. The following procedure is recommended:
a.
Remove dirt, mud, and other marks from exterior surface with clean water.
b.
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 rub surface harshly.
c.
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.
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.
