2-23. CLEANING ENGINE COMPARTMENT. Before cleaning the engine compartment, place a strip tape on
the magneto vents to prevent any solvent from entering these units.
a. Place a pan under the engine to catch waste.
b. 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.
CAUTION
Do not spray solvent into the alternator, starter, air intake, and alternate air
inlets.
c. 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.
d. Remove the protective covers from the magnetos.
e.
Lubricate controls, bearing surfaces, etc. per Lubrication Chart.

material over the wheel and brake assembly.
a. Place a pan under the gear to catch waste.
b. Spray or brush the gear area 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.
c. Allow the solvent to remain on the gear from five to ten minutes, then rinse the gear with additional
solvent and allow to dry.
d. Remove the cover from the wheel and remove the catch pan.
e.
Lubricate the gear per Lubrication Chart.
2-25. CLEANING EXTERIOR SURFACES. 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. Cover the mast of the gear back-up
extender. To wash the airplane, the following procedure may be used:
a. Flush away loose dirt with water.
b. Apply cleaning solution with a rag, sponge or soft bristle brush.
c.
To remove stubborn oil and grease, use a cloth dampened with naptha.
d. Where exhaust stains exist, allow solution to remain on the surface longer.
e.
Any good automotive wax may be used to preserve the painted surfaces. Solt cleaning cloths or
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.
2-26. CLEANING WINDSHIELD AND WINDOWS
a. Remove dirt, mud, etc. from exterior surfaces with clean water.
b. Wash with mild soap and warm water or an aircraft plastic cleaner using a soft cloth or sponge and a
straight rubbing motion. Do not harshly rub surfaces.
