The Invisible Glass 91411-6PK Glass Stripper is designed specifically to remove tough hard water spots and mineral deposits from auto glass, making it a good choice if your windshield or windows have stubborn water stains. It works by stripping away waxes, oils, silicones, and road film, which helps prepare the glass for applying rain repellents or ceramic coatings. The product comes in a paste form with an applicator sponge, making it fairly easy to apply even for beginners.

One notable feature is that it does not leave streaks or residue, so the glass appears clear and smooth after use.
