CLEANING AND CARE
EXTERIOR CARE
The painted surfaces of the airplane have a long-lasting, all-weather finish and should require no buffing or rubbing
out in normal conditions. However, it is desirable to wax and polish it to preserve the outstanding exterior finish.
The paint can be kept bright simply by washing with water and mild soap. Avoid abrasive or harsh detergents.
Rinse with clear water and dry with terry cloth towels or chamois. Oil and grease spots may be removed with
kerosene or mineral spirits.
NOTE
No commercial paint removers are to be used on any airframe component unless
specific prior approval has been received from the factory. (See Maintenance
Manual.)
If you choose to wax your airplane, use a good automotive-type wax applied as directed. The use of wax in areas
subject to high abrasion, such as leading edges of wings and tail surfaces, propeller spinner, and blades, is
recommended.
WINDSHIELD AND WINDOW CARE
It is recommended that you keep the Plexiglas in the windshield and cabin window clean and unscratched. The
following procedures are recommended:
1.
If large deposits of mud and/or dirt have accumulated on the Plexiglas, flush with clean water. Rubbing
with your hand is recommended to dislodge excess dirt and mud without scratching the Plexiglas.
2.
Wash with soap and water. Use a sponge or heavy wadding of soft cloth. DO NOT rub, as the abrasive
action in the dirt and mud residue will cause fine scratches in the surface.
3.
Grease and oil spots may be removed with a soft cloth soaked in kerosene.
4.
After cleaning, wax the Plexiglas surface with a thin coat of hard polish or wax.
5.
If a severe scratch or marring occurs, jeweler’s rouge is recommended. Follow directions, rub out scratch,
smooth, apply wax and buff.
CAUTION
NEVER USE GASOLINE, BENZENE, ALCOHOL, ACETONE, CARBON
TETRACHLORIDE, FIRE EXTINGUISHER FLUID, ANTI-ICE FLUID, LACQUER THINNER
OR GLASS CLEANER TO CLEAN PLASTIC. THESE MATERIALS WILL DAMAGE THE
PLASTIC AND MAY CAUSE SEVERE CRAZING.
