Cleaning Exterior Lamps/Lenses; Finish Care - GMC Sierra Denali Classic 2007 Owner's Manual

Cleaning Exterior Lamps/Lenses

Use only lukewarm or cold water, a soft cloth and
a car washing soap to clean exterior lamps
and lenses. Follow instructions under Washing
Your Vehicle on page 427.

Finish Care

Occasional waxing or mild polishing of your
vehicle by hand may be necessary to remove
residue from the paint finish. You can get
GM-approved cleaning products from your dealer.
See Vehicle Care/Appearance Materials on
page 433.
If your vehicle has a "basecoat/clearcoat" paint
finish, the clearcoat gives more depth and gloss
to the colored basecoat. Always use waxes
and polishes that are non-abrasive and made for
a basecoat/clearcoat paint finish.
428
Notice: Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
finish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint finish on your vehicle.
Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and tar, tree
sap, bird droppings, chemicals from industrial
chimneys, etc., can damage your vehicle's finish if
they remain on painted surfaces. Wash the vehicle
as soon as possible. If necessary, use non-abrasive
cleaners that are marked safe for painted surfaces
to remove foreign matter.
Exterior painted surfaces are subject to aging,
weather and chemical fallout that can take their
toll over a period of years. You can help to
keep the paint finish looking new by keeping your
vehicle garaged or covered whenever possible.
