Abstract
A cleaning device includes a porous body and a dispensing reservoir disposed within the porous body. The dispensing reservoir has at least one opening being disposed at a predetermined location along a length of the dispensing reservoir such that a rate at which the solution flows into the porous body varies based specific orientations of the porous body. A perforated fluid supply conduit is also disposed within the porous body and extends alongside the dispensing reservoir, the perforated fluid conduit having a plurality of perforations. The dispensing reservoir and the perforated fluid supply conduit are not directly fluidly coupled.
