Abstract
A standard toilet bowl brush, having a wire loop frame, sometimes lying in a slightly curved plane, supporting encompassing bristles, and with an elongated handle, is converted, temporarily, into a steel wool brush by an adaptor spider which embraces the larger dimension of the brush and projects a forwardly and upwardly canted lance upon which a steel wool or other harsh scrub pad is impaled to enable under-the-rim scrub action where hard deposits build up and discolor from water deposits.
