12-20-01 Exterior Cleaning
The painted surface of the aircraft features a long lasting, all-
weather finish and should require no buffing or rubbing out
in normal conditions. However, it is desirable to wash and
polish it to preserve the outstanding exterior. Cleaning is
best accomplished with cool water, mixed with a mild aircraft
detergent, if required.
N O T I C E Do not use so called "mild" household detergents to
wash aircraft exterior. Such detergents may damage
finish and corrode aluminum components.
In order to remove especially heavy dirt from the wing
leading edges due to insect splatter and the like, it is good
practice to perform cleaning immediately after the flight,
since deposits of this kind are more difficult to remove when
dry. All lubricated components are to be covered before
cleaning.
Roughly twice a year, the complete surface should be treated
with a non-silicone car polish and repolished to high gloss.
But do not apply wax or use pre-wax cleaners during initial
paint curing period. Use only mild aircraft detergent and
cool water when washing exterior during the first 90 days
after repainting.
N O T I C E Never use cleaning agents containing silicone!
In order to maintain good visibility at all times, the canopy
Plexiglas should be given good care and kept clean at all
times. Techniques and materials used to clean glass should
be avoided since Plexiglas is softer than glass and subject to
damage by solvents and abrasive glass cleaning agents.
Therefore pay particular attention to using ample water
applied with clean sponges and leather, otherwise even the
smallest dust particles will tend to scratch the glazing.
N O T I C E Never polish plexiglass dry!
