Abstract
A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.
