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.

A sponge product for cleaning a work surface, comprising:
- an open-cell melamine foam body layer having an upper surface and an opposed lower surface in parallel spaced relation to one another, a front wall and opposed rear wall that are parallel to one another, and a first sidewall and opposed second sidewall, wherein at least one of the front wall, rear wall, first sidewall or second sidewall is inclined and at an acute angle relative to the upper surface of the body layer, and
- an abrasive layer adjacent only to the upper surface of the melamine foam body layer and attached thereto to form a unitary product, wherein the abrasive layer is selected from a material comprised of a reticulated abrasive foam or a nonwoven fibrous mass, and the abrasive layer has an upper surface and an opposed lower surface that are parallel to one another, a front wall and an opposed rear wall that are parallel to one another, and a first sidewall and an opposed second sidewall, and at least one of the front wall, rear wall, first sidewall or second sidewall of the abrasive layer form 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, such that the working edge remains flat against the work surface when a force is applied to the sponge product.
