A mild abrasive cream cleaner designed to work where other cleaners won't. It utilizes nano-sized particles to penetrate into small surface pores where it can effectively work to remove surface stains and residues. Effective for cleaning all stone and tile surfaces. Also removes factory-applied waxes, coating sealers, light grout residue (including epoxy), rubber and pencil marks, light mineral deposits, ground-in dirt and most sealer residues. NanoScrub® is non-toxic, non-flammable and non-acidic.
