GMC 2008 Acadia - Manual (Page 407)

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 the
vehicle. Avoid using high pressure washes closer
than 12 inches (30 cm) to the surface of the vehicle.
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
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 5-92.
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 approved cleaning products from your
dealer/retailer. See Vehicle Care/Appearance Materials
on page 5-97.
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.
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.
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 chrome polish on
chrome or stainless steel trim, if necessary.
