ABSTRACT:
A surface treating pad having a renewable working surface comprises a base layer upon which is removably fastened at least one unitary stack comprising a plurality of thin layers of lofty nonwoven abrasive material. The layers on the stack are removably fastened together and to the base layer so that individual layers may be easily separated from the stack or from the base layer to expose a fresh surface treating working face without damage to the remainder of the pad. The pads are particularly suited for treating floors.
