Product Expert Notes
Rinse the sponge often and wring it nearly dry before each pass so it lifts grout haze instead of dragging it across joints. The large 2 in. thickness keeps your hands out of the grout and the shape resists collapsing during repeated wringing. Replace the sponge when edges begin to tear, as worn edges can smear joints.
Wear waterproof gloves and eye protection when working with cement-based grout, which is alkaline and can irritate skin.
