Half sponge and half scrub increase 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 a large water-holding capacity. The softness of the sponge prevents digging, scratching, or marring new grout while cleaning up the tiles around it. The large, 7-1/2" x 5" x 2" sponge fits comfortably in your hand. Box of 125 sponges. Proudly made in the USA.
