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.
