Marblelife tile & grout cleaner is designed for regular cleaning of ceramic and porcelain tile and grout. It goes where others can't, penetrating deep into the minute pores of tile and grout surfaces. Delivers a neutral detergent and surfactants to dissolve the oils and debris trapped inside, which may then be wiped away, streak-free. Eliminating the oils and debris from the stone's pores allows the surface to shine with all of its natural beauty. Works well on all types of natural and man made tile and grout surfaces as well as finished wood flooring. 32 oz easy-to-use spray bottle. Refer to Model No. 0739 (SKU 615070) for gallon refill.
