ABSTRACT:
A sponge cleaning utensil has an inner core for holding a cleaning agent and encouraging the cleaning agent to be continually in contact with water drawn into the inner core preferably via a plurality of conduits which are preferably molded into the sponge material. The inner core is fabricated so as to be substantially larger than the solid cleaning agent therein allowing the cleaning agent free movement within the core. This allows water to freely surround the cleaning agent creating rich lather production and the lather to be easily removed to the surface. The conduits preferably have openings at a plurality of positions on the sponge exterior surface so as to provide even moisture and lather to all portions of the sponge exterior including the edges.
