Abstract
Antimicrobial, hard surface cleaning compositions that effectively clean and reduce microorganisms on a surface without resulting in unacceptable filming and/or streaking residue on the surface, generally comprise (a) cationic antimicrobial active; (b) nitrogen-containing polymer; and (c) surfactant. Preferred antimicrobial, hard surface cleaning compositions for use in no-rinse cleaning methods comprise (a) from about 0.001% to about 0.5%, by weight of the composition, of surfactant; (b) cationic antimicrobial active; and (c) nitrogen-containing polymer. Methods of cleaning and reducing microorganisms on hard surfaces comprises contacting the surfaces with such compositions and preferably allowing the compositions to dry on the surface without rinsing the composition from the surface using water or other rinsing solution.
