Grunge Attack^® is a concentrated pH-balanced tile and grout cleaner that cleans surface soils with penetrating action that actually lifts dirt and stains off the surface. It penetrates into grout to clean soap scum, mold, mildew, algae, grease, oil, and lime deposits. Grunge Attack^® is safe for daily cleaning, but it’s strong enough to clean stubborn stains quickly. This rinse-free formula is slip-resistant on floors and is safe for use on food-handling surfaces. For large areas, use with the Oreck Orbiter and Union Mix Brush.
