Cleaning Glass Surfaces 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 theinside rear window, since they may have to be scraped off later. If abrasive cleaners areused on the insideof the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid. Grime from the windshield will stick to thewiper 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.
