CLEANING AND CARE
WINDSHIELD AND WINDOWS
The plastic windshield and windows should be cleaned with an airplane
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 flannel
cloths.
CAUTION
NEVER USE GASOLINE, BENZENE, ALCOHOL,
ACETONE, FIRE EXTINGUISHER, ANTI-ICE FLUID,
LACQUER THINNER OR GLASS CLEANER TO CLEAN
THE PLASTIC. THESE MATERIALS WILL ATTACK THE
PLASTIC AND MAY CAUSE IT TO CRAZE.
If a windshield cleaner is not available, the plastic can be cleaned with
soft cloths moistened with Stoddard solvent to remove oil and grease.
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 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.
