Cleanliness is a major prerequisite to adequate inspec-
tion and maintenance of an aircraft. Cleanliness en-
hances the appearance of an aircraft and reduces the
probability of corrosion.
1. EXTERIOR
A. Before washing aircraft exterior, cover brake
discs, pitot head, and static ports.
B. Flush away loose dirt and mud.
C. Wash exterior with a mild aircraft detergent in
cool water and a soft cleaning cloth or chamois. Rinse
away soap film.
-CAUTION-
Do not use so called “mild household” deter-
gents to wash aircraft exterior. Such deter-
gents may damage finish and corrode alumi-
num components.
-CAUTION-
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.
D. To remove heavy oxidation film, use a pre- wax
cleaner.
E. Apply an exterior- finish wax recommended for
protection of urethane enamel. Apply a heavy coating
of wax to leading edges of wings, empennage, and
nose section to reduce drag and abrasion.
-CAUTION-
When fuel, hydraulic fluid, or other fluid con-
taining dye is spilled on painted surfaces,
remove it at once to prevent staining. Flush
away spilled battery electrolyte immediately
with water. Treat exposed area with bicarbon-
ate of soda solution followed by thorough
washing with a mild aircraft detergent
solution.
F. Blow moisture away from areas that may trap &
accumulate water, IE. engine mount at firewall attach
points (inside cupped portion of tubing).
2. WINDSHIELDS, WINDOWS AND DOORS
A. Flush windshield and windows with water prior
to wiping. Never wipe while dry.
B. Remove grease or oil with a soft cloth saturated
in kerosene.
-CAUTION-
Never use gasoline, benzene, carbon tetra-
chloride, alcohol, acetone, fire extinguisher
fluid, lacquer thinner, deicing fluids, or
household window cleaning sprays on win-
dows or windshields. Such solvents will
soften or craze the Plexiglass surface.
C. Clean windows and windshields with an anti-
static Plexiglass cleaner.
-NOTE-
Minor scratches or abrasions may be polished
out by using Plexiglass re- surfacing kits, i.e.,
Micro- Mesh, available from aircraft accessory
suppliers.
D. Check all door seals for damage that could
cause leakage.
E. Check both cabin doors and baggage door
mechanism for proper working order.
3. ENGINE COMPARTMENT
Accumulation of dirt and oil within the engine compart-
ment creates a fire hazard and hampers inspection pro-
cedures.
A. Wash engine cowling and engine compartment
down using a non- flammable solvent.
B. Dry engine cowling and engine compartment af-
ter washing.
4. CABIN INTERIOR
Use normal household cleaning practices for routine in-
terior care. Refer to Chapter 25 for detailed cabin interi-
or care instructions.
