ABSTRACT:
A cleaning device (10) for bath tubs, shower enclosures, swimming pools, and the like, comprises a more rigid support block (12) attached in a cavity (40) formed in a sponge block (14). A support-block bottom surface (22) is substantially flat and is substantially parallel to a substantially flat sponge bottom outer surface (36). A support-block sidewall surface (24) extends upwardly from said support block bottom surface when said support block bottom surface is horizontal but includes an inwardly beveled transition portion (30). A bottom edge area (38) of a sponge block outer surface (32) is spaced substantially further from the support block than other portions of the sponge outer surface. There is a dimple (50) in the sponge bottom outer surface positioned below the cavity. A maximum spacing of the sponge-block outer surface from a support-block outer surface (20) is in a range of from one-half inch to two inches, with the bottom edge area 38normally being one and one half inches therefrom and most of the remainder of the sponge block outer surface being around one inch therefrom. The support block can be molded in the cavity as well as held therein by protrusions on the outer surface of the support block.
