Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
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 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 GM
Windshield Cleaner, Bon Ani@ Powder (non-scratching
glass cleaning powder), GM
P a r t No. 105001 1. 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.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every
six months. During very cold, damp weather
more frequent application may be required. (See
"Recommended Fluids and Lubricants" in the Index.)
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle's finish is to
keep it clean by washing it often with lukewarm or
cold water.
