Aqua Mix Nanoscrub is an abrasive cream cleanser designed to work where other cleaners won't. It utilizes NanoSTTM (nano-sized particles) to penetrate below tough stains, dissolve and lift them out. Especially effective for cleaning rough or textured surfaces. Also removes waxes and floor finishes, 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. Available in quart and gallon sizes.
