Mr Hard Water™ Liquid Glass Polish is destined to become the work-horse for glass polishing. Suspended in deionized water, these "cerium oxide" like polishing particles feature nano sized minerals optimized for glass polishing. Liquid Glass Polish can be used as a first pass polish, final stage polish, or to remove hazing, etching, and light swirl marks. Simply spray and polish. It works well with both steel wool pads, nylon pads, and the NEW Liquid Nylon Pad. All natural, safe, and easy to work with.
