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. 105001 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.
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.
Don't wash your vehicle in the direct rays of the sun. Don't use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (mild
detergent) soaps. Don't use cleaning agents that contain acid or abrasives.
All cleaning agents should be flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the finish with a soft, clean chamois or
a 100%
cotton towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water to enter your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get GM approved cleaning
products from your dealer. (See "Appearance Care and Materials" in the
Index.)
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep their luster. Washing
with water is all that is usually needed. However, you may use GM Chrome
Polish on chrome or stainless steel trim, if necessary.
