The present invention relates to compositions having durable antimicrobial activity. The compositions include a carbonate/bicarbonate salt of a quaternary ammonium cation, an organic acid, hydrogen peroxide, a surfactant and a polymer. The polymer is selected from cationic amine polymer-epichlorohydrin adduct, cationic amine polymer-epichlorohydrin resin, poly(methacrylamidopropyltrimethylammonium)chloride, poly(bis(2-chloroethyl)ether-alt-1,3-bis(dimethylamino)propyl)urea, poly(diallyldimethylammonium)chloride, poly(t-butyl acrylate co-ethyl acrylate co-methacrylic acid), polyethylene oxide, polyquaternium-16, polyquaternium-22, polyquatemium-67 and combinations thereof. The surfactant is selected from cationic surfactants, non-ionic surfactants, zwitterionic surfactants and combinations thereof.
