Grout Renu is used when all other cleaners have failed. It works on the acid side of the pH scale removing soils and stains on grout, and tile that have been neglected for years. Grout Renu actually removes a very thin layer of grout, taking with it all hard water deposits, soap scum and efflorescence. Grout Renu does all this without the unpleasant fumes of harsh acids. Keep a gallon of Grout Renu on your truck so you’ll be prepared for even the most extreme tile and grout cleaning situation.
Cleaning Instructions: Pretest each surface in an inconspicuous area to determine suitability. Note: Mask off all surfaces which may come in contact with pre-spray, especially metal as it will etch the surface. Grout Renu will damage marble, limestone, and other acid sensitive materials. Do not mix with other chemicals, and store only in closed original container.
