It's the newest sensation sweeping the nation. Renew your grout in seconds. Works on all ceramic and porcelain tiles. Removes: Haze, Mold, Mildew, Soap scum, Coffee, Tea, Kool-Aid, plus so much more! Grout Sensation restores grout to its original color without a heavy chemical odor. This product will not leave residue or sand particles. It's very easy, safe, and effective for use on all ceramic and porcelain tiles. While mopping with floor cleaner only removes the top surface dirt, Grout Sensation works deeply into the grout lines to loosen and lift away dirt, mold, mildew, and bacteria that deeply stain your grout over time. It can even remove tough stains like permanent marker. The best way to apply Grout Sensation is either straight from the bottle or with a pump sprayer onto the tile's grout lines. You'll begin to see the strong foaming action as the underlying particles are brought to the surface for easy wiping. For tough stains, lightly agitate the grout lines with a deck brush to restore the grout's appearance. Follow up by mopping thoroughly with clean water and enjoy the look of your brand new floor. Includes: 1 x Grout Sensation Tile and Grout Concentrated Formula Cleaner - 32 oz.
