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 (non-detergent) soaps.
Aluminum Wheels (If So Equipped)
Don’t use cleaning agents that contain acid or abrasives.
All cleaning agents should be flushed promptly and not Your alUminUm wheels have a protective Coating SiIdar

of your car. Don’t use strong

or other abrasive
towel to avoid surface scratches and water spotting. cleaners on them because you could damage this
High pressure car washes may cause water to enter your
vehicle. coating. After rinsing thoroughly, a wax may be applied.
Finish Care
Occasional waxing or mild polishing
of your Buick may
be necessary to remove residue from the paint finish.
You can get
GM approved cleaning pr,oducts from your
dealer. (See “Appearance Care and Materials” in the
Index.)
Your Buick has
a “basecoat/clearcoat” paint finish. The
clearcoat gives more depth and gloss to the colored
basecoat.
if you have aluminum wheels, don’t use an
automatic vehicle wash that has hard silicon
carbide cleaning brushes. These brushes can
take
off the Drotective coatina.
