Abstract
A cleaning card for use in cleaning internal surfaces of machine components includes a substrate having a central plane between opposed surfaces thereof, a machine direction dimension defined between opposed leading and trailing end edges and a transverse direction dimension defined between opposed side edges. The opposed surfaces each have a plurality of discrete raised areas, each including a peak and an inclined peripheral leading wall including an edge remote from the peak. The peak of each raised area is further from the central plane than the edge of the inclined peripheral leading wall remote from the peak and leading walls of a plurality of discrete raised areas have edges defining openings therein for assisting in removing debris from the machine components.
