    Abstract: A multi-layer combination sponge includes a scrubbing layer and a cleaning layer that are each laminated to an intermediate layer. The intermediate layer is more compressible than the cleaning layer and the scrubbing layer, and a groove is formed around a perimeter of the sponge between the cleaning layer and the scrubbing layer. The layers are preferably coextensive, forming a nose portion at the front of the combination sponge and having rounded comers at the rear of the combination sponge. The cleaning and intermediate layers each have an approximately equal thickness, and the scrubbing layer has a thickness less than one-half as thick as either the cleaning layer or the intermediate layer.
