Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or
a liquid household glass cleaner will remove normal
tobacco smoke and dust films on interior glass.
See “Appearance Care and Materials” in the Index.
NOTICE:
Don’t use abrasive cleaners on glass, because
they may cause scratches. Avoid placing decals
on the inside rear window, since they may have
to be scraped off later. If abrasive cleaners
are used on the inside of the rear window,
an electric defogger element may be damaged.
Any temporary license should not be attached
across the defogger grid.
Cleaning the Outside of the Windshield,
Backglass and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with a full
-strength
glass cleaning liquid. The windshield is clean if beads
do not form when you rinse it with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean the blade by
wiping vigorously with a cloth soaked in full
-strength
windshield washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
