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.
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, you may use
GM Chrome Polish on
chrome or stainless steel trim,
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.
Aluminum Wheels (If So Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with
clean water. After
rinsing thoroughly, dry with
a soft clean towel. A wax
may
then be applied.
The surface of these wheels is similar
to the painted
surface of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes
on them because you could
damage the surface.
Don’t take your vehicle through an automatic vehicle
wash that has silicon carbide tire cleaning brushes.
These brushes can also damage the surface of
these wheels.
