Half sponge and half scrub means clean up in half the time. Hydra sponge on one side to wipe off excess grout. Coarse plastic foam scrubber on the opposite side to remove grout haze. The sponge part has large water holding capacity. The softness of the sponge prevents digging , scratching or marring of new grout while cleaning up the tiles around it.
