ABSTRACT:
A foam scrubbing device incorporating a cleanser formed from two layers of foam material having different characteristics heat sealed along their respective peripheries is provided. The two layers of foam material have different cell coarseness to provide varying degrees of abrasiveness, permeability and flexibility. The device is formed with the different layers of foam material having different thicknesses to permit substantially equal amounts of cleanser to pass through each layer.
