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
R
Powder (non - scratching
glass cleaning powder), GM Part No. 1050011. The
windshield is clean if beads do not form when you rinse
it with water.
If you use a glass treatment or conditioner containing
ethyl alcohol or ethyl sulfate on your glass, be sure to
remove the acrylic roof panel, if so equipped. These
products may damage the panel.
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.)
Cleaning a Removable Roof Panel
Special care is necessary when cleaning, removing
and/or storing the roof panel.
D Flush with water to remove dust and dirt, then dry
the panel.
D Clean the panel with GM Glass Cleaner. Leave the
cleaner on the panel for one minute, then wipe the
panel with a soft, lint
- free cloth.
D Don’t use abrasive cleaning materials.
