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


Mr Hard Water® Sealer seals and protects shower doors and windows against the build-up of soap and hard water eliminating the need for a daily squeegee. It also protects shower door glass and windows from the etching effects of hard water stains preserving your raw material investment.  Mr Hard Water® Sealer makes subsequent cleaning much easier because it provides a "Teflon-like" coating that prevents the adherence of stain creating substances such as hard water, soaps, and dirt.
