Cessna 1973 172 - Exterior Surface Maintenance

(3) Install a surface control lock over the fin and rudder.
(4) Install a pitot tube cover.
WINDSHIELD - WINDOWS.
The plastic windshield and windows should be cleaned with an aircraft
windshield cleaner. Apply the cleaner sparingly with soft cloths, and rub
with moderate pressure until all dirt, oil scum and bug stains are re-
moved. Allow the cleaner to dry, then wipe it off with soft flannel cloths.
If a windshield cleaner is not available, the plastic can be cleaned
with soft cloths moistened with Stoddard solvent to remove oil and grease.
NOTE
Never use gasoline, benzine, alcohol, acetone, carbon
tetrachloride, fire extinguisher or anti-ice fluid, lacquer
thinner or glass cleaner to clean the plastic. These ma-
terials will attack the plastic and may cause it to craze.
Follow by carefully washing with a mild detergent and plenty of water.
Rinse thoroughly, then dry with a clean moist chamois. Do not rub the
plastic with a dry cloth since this builds up an electrostatic charge which
attracts dust. Waxing with a good commercial wax will finish the clean-
ing job. A thin, even coat of wax, polished out by hand with clean soft
flannel cloths, will fill in minor scratches and help prevent further
scratching.
Do not use a canvas cover on the windshield unless freezing rain or
sleet is anticipated since the cover may scratch the plastic surface.
PAINTED SURFACES.
The painted exterior surfaces of your new Cessna have a durable,
long lasting finish and, under normal conditions, require no polishing or
buffing. Approximately 15 days are required for the paint to cure com-
pletely; in most cases, the curing period will have been completed prior
to delivery of the airplane. In the event that polishing or buffing is re-
quired within the curing period, it is recommended that the work be done
by someone experienced in handling uncured paint. Any Cessna Dealer
can accomplish this work.
