To remove dust and loose dirt from the upholstery and carpet, clean
the interior regularly with a vacuum cleaner.
Blot up any spilled liquid promptly with cleansing tiszue or rags.
Donrt pat the spot; press the blotting material firmly and hold it for sev-
eral seconds. Continue blotting until no more liquid is taken up. Scrape
off sticky materials with a dull knife, then spot-clean the area.
Oil spots may be cleaned with household spot removers, used spar-
ingly. Before using any solvent, read the instructions on the container
and test it on an obscure place on the fabric to be cleaned. Never satu-
rate the fabric with a volatile solvent; it may damage the padding and
backing materials.
Soiled upholstery and carpet may be cleaned with foam-type detergent,
used according to the manufacturerts instructions.
To minimize wetting
the fabric, keep the foam as dry as possible and remove it with a vacuum
cleaner.
If your airplane is equipped with leather seating, cleanirg of the seats
is accomplished using a soft cloth or slpnge dipped in mild soap suds.
The soap zuds, used sparingly, will remove traces of dirt and grease.
The soap should be removed with a clean damp cloth.
The plastic trim, headliner, instrument panel and control knobs need
only be wiped off with a damp cloth. Oil and grease on the control wheel
and control loobs can be removed with a cloth moistened with Stoddard
solvent.
Volatile solvents, such as mentioned in paragraphs on care of
the windshield, must never be used since they soften and craze the plastic.
