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. Cleaning Removable Roof Panel Special care is necessary when cleaning, removing and/or storing the roof panel. • Flush with water to remove dust and dirt, then dry the panel. Cleaning 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 a full-strength glass cleaning liquid. 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. • 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. • Do not use abrasive cleaning materials If water drops are frequently allowed to dry on roof panel, impurities in the water will adhere to the top. These impurities may etch or mar the finish. When the panel gets wet, you should dry it off. Notice: If you use a glass treatment and/or conditioner that contains ethyl alcohol or ethyl sulfate on the roof panel, you could damage the panel. The repairs would not be covered by your warranty. Only use a GM-approved glass cleaner on the roof panel. 5-87
