Glass
Glass should be cleaned often. GM Glass Cleaner (GM
Part
No.
1050427) or a liquid household glass cleaner
will
remove normal tobacco smoke and dust films on
interior glass.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off
later.
If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any
temporary license should not be attached across the
defogger grid.
Cleaning the Outside
of
the
Windshield and Wiper Blades
If
the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon Ami’ Powder (non-scratching
glass cleaning powder), GM Part
No.
105001
1.
The
windshield is clean
if
beads do not form when
you
rinse
it with water.
Grime from the windshield
will
stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked
in
full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Index.)
