1. A wipe comprising:
- a. a subbstrate which comprises a nonwoven material,b. wherein said substrate is impregnated with a polycationic polymer selected from the group consisting of polyethyleneimine, copolymers of polyethyleneimine and combinations thereof;
wherein said polymer has a molecular weight ranging from about 500,000 to about 2,000,000; and
c. wherein said wipe is dry.

Abstract
Incorporating dirt-attracting polycationic polymers, such as polyethyleneimines, into cleaning wipes, mop pads, and similar substrates, improves dirt pick-up and retards redeposition of the dirt back onto the cleaned surface. The polymers can be incorporated directly into the non-woven substrates or they can be formulated with a cleaning composition for use with the substrate. The substrate containing the dirt-attracting polycationic polymers can be employed to clean hard and soft surfaces. The presence of the dirt-attracting polycationic polymers also facilitates biocide release from the substrates.
