Abstract
A cleaning pad is adapted to be releasably retained on a cleaning implement which includes on its cleaning head either multiple strips of pile-type fastener material or a plurality of attachment structures. The cleaning pad includes a top layer constructed of polyethylene and a bottom layer constructed of rayon. The top and bottom layers are affixed together along their peripheries by a bond line so as to define an enclosed pocket therebetween which is sized and shaped to receive a middle layer constructed of wood pulp paper. Multiple strips of hook-type fastener material are secured on the top layer and are adapted to releasably engage complimentary strips of pile-type fastener material on the cleaning implement. One or more mounting tabs are secured on the bottom layer and are adapted to releasably engage complimentary attachment structures on the cleaning implement. Each mounting tab can be disposed between a retracted, or folded, position and an extended, or unfolded, position.
