ZEROREZ® offers a remarkable and GREEN solution to cleaning your tile, countertops, glass surfaces, natural stone and other hard floors surfaces to clean, protect against harmful pathogens and keep them looking their best. Traditional tile and surface cleaning employs soap and detergents to break up the soil, but this leaves an invisible residue film on your countertops, glass and floors. This film actually attracts dirt and over time discolors the grout and hard surfaces. Now, you don't have to scrub your grout lines for hours at a time or worry about unclean and unprotected surfaces - ZEROREZ® has the solution.
