ABSTRACT:
A cleaning card has a flat, semirigid base with a first and second material mechanically bonded to the side surfaces thereof. The first material is an abrasive substantially impenetrable material and the second material is a soft spunlaced fabric of high absorptive capacity. The differences in physical qualities of the first and second materials allow for one card to be used both as frequent cleaning card as well as a corrective cleaning card and provides a cleaning card that enables operation of the machine quickly after cleaning thereof.
