GMC T-Series 2007, Owner'S Manual, Page: 272 / 356

Windshield and Wiper Blades
Clean the outside of the windshield 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 cleaning 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 Wheels
The vehicle may have aluminum wheels.
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
GM-approved cleaners on 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: Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
The surface of these wheels is similar to the
painted surface of the vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because the surface could
be damaged. Do not use chrome polish on
aluminum wheels.
