WINDOWS: COATED GLASS When using a polisher on sensitive glass such as residential or commercial windows that may have an external coating (Low-E, anti-reflective, pyrolytic, etc.), then Mr Hard Water 2 Liquid Glass Polish should be your first choice.  The Liquid Glass Polish contains polishing particles specifically designed for glass and is composed of polishing particles that are 50 times smaller than traditional hand cleaners.  It can be used as a first polish or final polish after using the powder. Watch our instruction videos to see how both remove tough hard water stains.  The Liquid Glass Polish is ideal for polishing away acid etching, white haze, and light swirl marks.  Both the powder and the liquid can be used with both the nylon and the steel wool pads.  I personally prefer the Liquid with a Steel Wool Pad!


Mr Hard Water® Glass Sealer is a durable, easy-to-apply sealer that protects shower doors and windows from soap scum and hard water build-up.  Mr Hard Water® can be safely used on glass surfaces, mirrors, metals, tile, fiberglass, porcelain, and plastic.

Application:  1. Clean and dry the surface.  2. Spread and buff the sealant evenly across the surface using a soft cloth, sponge, microfiber towel, or sealant applicator taking care not to miss any spots.  Apply two coats if necessary. 3. Let the sealer dry for three to five minutes until a haze appears.  4. Buff off the remaining haze by rinsing with a wet towel.  Watch the water bead off!  5. Use a squeegee or dry cloth to remove the remaining water from the glass surface. 6. Re-apply as needed.
