Cleaning Exterior Lamps/Lenses; Finish Care - GMC T-Series 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 270.

Finish Care

Occasional waxing or mild polishing of the 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 274.
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 the 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. The paint finish can be
kept looking new by keeping the vehicle garaged
or covered whenever possible.
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, chrome polish on
chrome or stainless steel trim can be used
if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or
chrome polish, steam or caustic soap to clean
aluminum. A coating of wax, rubbed to high polish,
is recommended for all bright metal parts.
