A highly absorbant, hydrophillic cleaning sponge for washing away cementitious grouts from walls and floors after grouting. The design of the sponge allows it retain less water when cleaning tiles as to not over saturate grout joints which could lead to accidental grout removal and grout effloresence. The segmented sponge helps to remove grout residue and rinse the sponge more efficiently. This version of the hydro sponge board features velcro backing for easy replacement of hydro sponges.
