Abstract
A moderately flexible laminate sheet article 30, capable of simultaneously cleaning both inner surfaces of slots and cavities of credit card readers, fax machines and the like, and in particular the scanners, sensors and printers residing therein, having a three layer structure, comprising two outer layers 21 and 23, that provide outer surface cleaning means, and comprising natural or synthetic, woven or nonwoven fibers, spot bonded to a moderately flexible, resilient center layer 22, comprising natural or synthetic, woven or nonwoven fibers, film or foam, wherein said spotbonds comprise 2% to 99% of bondable area. The laminate sheet article 30 has sufficient stiffness and resilience to prevent its wrinkling, buckling, crumpling or kinking while in use, and has utility for cleaning surfaces in its dry, or when saturated with liquids, in its wet state.
