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 end edges and a transverse direction dimension defined between opposed side edges. The substrate includes an embossment forming angled, substantially non-collapsible, elongate raised ridges on opposite sides of the cleaning card substrate, with the raised ridges being oriented at an angle to the machine direction for incrementally wiping transversely across the internal surfaces to be cleaned, which can include peripheral surfaces of idler rolls. Preferably the opposed surfaces of the substrate each have a plurality of discrete, raised and collapsible working areas for engaging and cleaning internal surfaces of machine components.
