Glass
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.
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 or other material may be on the
blade
or windshield.
Clean the outside
of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@
(GM Part No. 10500 I 1 ). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked
in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced when 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.
