Abstract: A sponge product for cleaning a work surface includes an open-cell melamine foam body layer having a front wall, rear wall, first sidewall or second sidewall that is inclined and at an acute angle relative to the upper surface of the body layer. An abrasive layer is adjacent the upper surface of the melamine foam body layer forming a unitary product. The abrasive layer has at least one of the front wall, rear wall, first sidewall or second sidewall forming an obtuse angle with the lower surface of the abrasive layer, and the abrasive layer upper surface and at least one front wall, rear wall, first sidewall or second sidewall forms a working edge having an acute angle, and the working edge remains flat against the work surface when a force is applied to the sponge product.
