Cleaning Glass Surfaces; Windshield And Wiper Blades - Pontiac 2001 Firebird Owner's Manual

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.
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.
6-56
Clean the outside of the windshield with GM Windshield
R
Cleaner, Bon Ami Powder (non
powder), GM Part No. 1050011. 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
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.
