B. Cleaning
CAUTION: IF PAINT IS LESS THAN SIX MONTHS, SEE “DUPONT IMRON 6000 PAINT
SYSTEM,” ABOVE.
CAUTION: DO NOT DIRECT ANY STREAM OF WATER OR CLEANING SOLUTION AT THE
OPENINGS IN THE PITOT HEAD, STATIC PORTS, ALTERNATE STATIC PORTS OR
FUSELAGE DRAINS.
The airplane should be washed with a mild soap and water. Harsh abrasives 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:
(1) Flush away loose dirt with water.
(2) Apply cleaning solution with a rag, sponge or soft bristle brush.
(3) To remove stubborn oil and grease, use cloth dampened with naphtha.
(4) Where exhaust stains exist, allow solution to remain on the surface longer.
(5) 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.
2. Cleaning
A. Exterior Surfaces - see “Aircraft Finish Care,” above, and “Windshield and Windows,” below.
B. Engine Compartment
Before cleaning the engine compartment, place strips of tape on the magneto vents to prevent any
solvent from entering these units.
(1) Place a pan under the engine to catch waste.
CAUTION: DO NOT SPRAY SOLVENT INTO THE ALTERNATOR, STARTER,
VACUUM PUMP(S), AIR INTAKE AND ALTERNATE AIR INLETS.
(2) With the engine cowling removed, spray or brush the engine with solvent or a mixture of
solvent and degreaser, as desired. It may be necessary to brush areas that were sprayed
where heavy grease and dirt deposits have collected in order to clean them.
(3) Allow the solvent to remain on the engine from five to ten minutes; then rinse the engine clean
with additional solvent and allow to dry.
CAUTION: DO NOT OPERATE ENGINE UNTIL EXCESS SOLVENT HAS EVAPORATED
OR OTHERWISE BEEN REMOVED.
(4) Remove the protective covers from the magnetos.
(5) Lubricate controls, bearing surfaces, etc., per Lubrication Charts,12-20-00.
