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.

A cleaning device (10) for bathtubs, shower enclosures, and the like comprises a sponge block having an outer surface which substantially defines a rectangular polyhedron in shape and which has a cavity (34) cut into a top surface thereof which is similarly shaped and oriented correspondingly as is the outer surface of the sponge block. A rigid support block (14), having an outer surface with length and breadth dimensions which are approximately the same as the size and shape of the length and breadth dimensions of a cavity surface, is adhered in the cavity by a chemical (cleaning), detergent, and water resistant, elastic, adhesive (18) and an elongated handle (16) is attached to a top surface of the support block. The sponge block is constructed of reticulated sponge material and distances between side, end, and bottom surfaces of the support block and the sponge outer surface fall in a range from 1/2 inch to 2. 5 inches. Bottom edges of the support block and the sponge block cavity are beveled surfaces (56, 45).
