A cleaning sponge roller is made of a polyvinyl acetal-based porous sponge having elasticity in a wet state and comprises a generally cylindrical roll body and a plurality of protrusions molded integrally on the periphery of the roll body. The cleaning sponge roller rotatingly cleans a material to be cleaned by contacting the top portions of the protrusions with the surface of the material and brushing off polishing residues found on the surface of the material. Each of the protrusions has a tapered protruding base portion extending from the periphery of the roll body, and a protruding end portion having almost the same sectional shape from the top end surface of the protruding base portion to the top portion.
