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. This replacement sponge can be used on its own or attached to hydro sponge boards for more leverage. Segments in the sponge help to remove grout residue and rinse the sponge more efficiently.
