CLEANING AND CARE
WINDSHIELD-WINDOWS
The plastic windshield and windows should be cleaned with an air-
craft windshield cleaner. Apply the cleaner sparingly with soft cloths,
and rub with moderate pressure until all dirt, oil scum and bug stains
are removed. Allow the cleaner to dry, then wipe it off with soft flan-
nel 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 te-
trachloride, fire extinguisher or anti-ice fluid, lacquer
thinner or glass cleaner to clean the plastic. These
materials will attack the plastic and may cause it to
craze.
Follow by carefully washing with a mild detergent and plenty of wa-
ter. 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 cleaning 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

buffing. Approximately 15 days are required for the paint to cure
(lllmpletely; in most cases, the curing period will have been completed
prior to delivery of the airplane. In the event that polishing or buffing
Is required within the curing period, it is recommended that the work
bo done by someone experienced in handling uncured paint. Ally Coxs-

Dealer can accomplish this work.
Generally, the painted surfaces can be kept bright by washing with
water and mild soap, followed by a rinse with water and drying with
«loths or a chamois. Harsh or abrasive soaps or detergents wh ich

corrosion or scratches should never be used. Remove stubborn
o il and grease with a cloth moistened with Stoddard solvent.
Waxing is unnecessary to keep the painted surfaces bright. How-
over, if desired, the airplane may be waxed with a good automotive
wax. A heavier coating of wax on the leading edges of the wings and
tail and on the engine nose cap and propeller spinner will help reduce
the abrasion encountered in these areas.
When the airplane is parked outside in cold climates and it is ne-
cessary to remove ice before flight, care should be taken to protect the
painted surfaces during ice removal with chemical liquids. A 50-50
solution of isopropyl alcohol and water will satisfactorily remove ice
uccummu
lations without damaging the paint. A solution with more
than 50% alcohol is harmful and should be avoided. While applying
the de-icing solution, keep it away from the windshield and cabin win-
dows since the alcohol will attack the plastic and may cause it to craze.
PROPELLER CARE
Preflight inspection of propeller blades for nicks, and wiping them
occasionally with an oily cloth to clean off grass and bug stains will
assure long, trouble-free service. Small nicks on the propeller, partic-
ularly near the tips and on the leading edges, should be dressed out as
soon as possible since these nicks produce stress concentrations, and if
ignored, may result in cracks. Never use an alkaline cleaner on the
blades; remove grease and dirt with carbon tetrachloride or Stoddard
solvent.
ENGINE CARE
The engine may be cleaned with Stoddard solvent, or equivalent,
then dried thoroughly.
