WINDSHIELD
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 I). 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
CADILLAC
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Hhicle
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
(non-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.
