Abstract
A self-sticking disintegrating cleansing block to be attached directly to a wall of a toilet bowl or urinal, above the water-line and in the stream of flush water, by pressing the cleansing block to the wall. The cleaning block includes 25% to 99% of a solid surfactant, and 1% to 25% of a liquid component. The cleansing block may include a substrate removably attached to a surface of the cleansing block. In use, the substrate is removed from the cleansing block and the exposed surface of the cleansing block is pressed to a surface in a position above any waterline that is contacted by a rinse liquid that disintegrates the cleansing block. Rinse liquid is then allowed to contact the cleansing block such that an amount of the cleansing block is mixed with rinse fluid to clean the surface or a liquid reservoir adjacent the surface.
