Want clean windows, mirrors, any type of glass surface? Without STREAKS?? Ever? And it even removes hairspray splatter. Use ALCOHOL.....Isopropyl Alcohol, that is. Clean like a marine - leave it to these guys and gals to make short time of cleaning. Take an old t-shirt pour some alcohol on it and wipe everything off of your glass surfaces. No build up, streaks, lint, or HARMFUL chemicals, and its cheap too!
