Abstract:
1. A method of forming and using a sponge to clean a work surface, the method comprising the steps of: providing a foraminous body layer of material having an upper surface and a lower surface; providing an abrasive layer of material having an upper surface and a lower surface; joining only the lower surface of the abrasive layer to only the upper surface of the foraminous body layer to form a unitary sponge body having one upper abrasive material layer and one lower foraminous body material layer; wherein the unitary sponge body includes a front wall having a foraminous body material layer and an abrasive material layer, a rear wall spaced apart from the front wall having a foraminous body material layer and an abrasive material layer, a first sidewall adjacent the front wall having a foraminous body material layer and an abrasive material layer and a second sidewall spaced apart from the first sidewall having a foraminous body material layer and an abrasive material layer, wherein at least one of the front wall, rear wall, first sidewall or second sidewall is inclined to form an acute angle with the abrasive material layer upper surface along a working edge; and applying a first force to the sponge body displaces the working edge towards an adjacent work surface.
