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.

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.)
