GMC 2008 Acadia - Manual (Page 408)

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.
Windshield, Backglass, and Wiper
Blades
Clean the outside of the windshield and backglass with
glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when you
clean the blades. Bugs, road grime, sap and a buildup of
vehicle wash/wax treatments may cause wiper
streaking. Replace the wiper blades if they are worn or
damaged.
Wipers can be damaged by:
• Extreme dusty conditions
• Sand and salt
• Heat and sun
• Snow and ice, without proper removal
Aluminum or Chrome-Plated Wheels
and Trim
Your vehicle may have either aluminum or chrome-plated
wheels.
Keep the 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.
Notice: Chrome wheels and other chrome trim may
be damaged if you do not wash your vehicle after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such as
ice and dust. Always wash your vehicle’s chrome
with soap and water after exposure.
Notice: If you use strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, you
could damage the surface of the wheel(s). The repairs
would not be covered by your warranty. Use only
approved cleaners on aluminum or chrome-plated
wheels.
The surface of these wheels is similar to the painted
surface of your vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners, cleaners
with acid, or abrasive cleaning brushes on them because
you could damage the surface. Do not use chrome polish
on aluminum wheels.
