Washing Your Vehicle; Cleaning The Outside Of Your Vehicle - GMC 2000 Sierra 1500 Pickup Owner's Manual

Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked in full
washer solvent. Then rinse the blade with water.
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.)

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.
Use a car washing soap. Don't use strong soaps or
chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. You can get
-
GM approved cleaning products from your dealer. (See
"Appearance Care and Materials" in the Index.) Don't
use cleaning agents that are petroleum based, or 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 an all cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
Cleaning Exterior Lamps/Lenses
Use lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions under "Washing Your Vehicle."
