20/20 is a powerful cleaning compound combining emulsifiers, surfactancts and solvents to provide rapid cleaning action without streaking on glass, mirrors, chrome, countertops, porcelain, tile, vinyl, acrylics, plastics and stainless steel. 20/20 will remove grease, oil, dirt and is harmless to paint, enamel, or lacquer when used as directed. It is especially effective on auto windshields and mirrors. Because it contains no ammonia, 20/20 is safe to use on plastics and tinted windows, and doesn't have the unpleasant odor that most glass and mirror cleaners have.
