GENERAL MAINTENANCE
CLEANING AND CARE OF AIRCRAFT
Keeping the performance, speed and durability that was built into your aircraft at the
factory requires more than casual attention. The accumulation of dirt and oil on the outside
and debris inside does affect these factors and can be a fire hazard as well. The first step to
proper maintenance is a clean aircraft.
EXTERIOR
Frequent washing is good for your aircraft finish, especially during the first few
months. Use any car soap or detergent with a soft cloth or sponge and plenty of clean water.
Drying should be done with a chamois. Accumulation of oil, grease and exhaust carbon
deposits should be removed frequently by using a soft cloth soaked in mineral spirits or other
neutral cleaner.
For general polishing, apply a good quality car polish or wax according to instructions.
Clean Plexiglas with plenty of soap and water using grit free soft cloth, chamois or sponge.
Use of a dry cloth on Plexiglas will not only cause scratches but will also build up an
electrostatic field which will attract dust to the surface. Blotting with a clean damp chamois
will remove the charge and the dust. After cleaning, polishing with a good Plexiglas cleaning
product such as "Mirror Glaz" will keep the glass clean and help polish out minor scratches.
INTERIOR
Floorboards should be vacuumed frequently and can be cleaned with any good rug
cleaner.
Care should be taken in the disposal of candy wrappers, paper scraps, cigarette
butts, etc. These can work their way under the floorboards and become a fire hazard and
moisture trap.
NOTE: While washing the aircraft, ascertain that all drain holes are open. Clean out
any debris blocking them. Accumulated water can be dangerous, so check behind the
baggage compartment frequently.
Textile upholstery may be cleaned using a vacuum cleaner. Grease and oil spots on
the upholstery should be treated with a spot remover or dry cleaning fluid. Do not use soap
and water on textile materials.
Vinyl upholstery may be cleaned using soft whisk broom or suds of any mild soap
(castile or olive oil base) in lukewarm water. Use water sparingly as the upholstery otherwise
requires a long time to dry if water trickles through the seam stitches.
