ABSTRACT:
A scrub brush with a handle by which the user grips the brush, a two-part scrubber portion which provides the scrubbing action, and a connecting staff between the handle and the scrubber. The scrubber may be of bristles, springy plastic mesh, rag-like or sponge material. The scrubber is designed so that a portion of the scrubber furthest from the handle can be compressed into a small diameter cylindrical shape of such dimension that a suitably sized ring of solid cleaning agent can pass over the compressed scrubber portion. When the compressed scrubber portion is released from its restraint, it expands to the original shape and size, thereby confining the ring of solid cleaning agent between the two scrubber portions.
