GMC 2008 Canyon - Manual (Page 365)

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.
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 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
