The present disclosure provides a method for killing pathogens on a surface, the method comprising applying to the surface a composition comprising: at least one quaternary ammonium compound; comprising one or more types selected from the group consisting of Polymers of monomeric units: cationic monomeric units, anionic monomeric units, amphoteric monomeric units, nonionic monomeric units, and combinations thereof, where present when the polymer comprises one or more nonionic monomeric units at least one cationic monomeric unit, amphoteric monomeric unit, or at least one anionic monomeric unit; a surfactant selected from the group consisting of cationic surfactants, amphoteric surfactants, nonionic surfactants, and combinations thereof; and optionally, an organic acid, wherein the composition has a pH of less than 5; and under standard temperature and pressure conditions, the composition reduces the amount of live pathogens on the surface by at least 0.5 log in about 60 minutes, wherein the pathogens Selected from bacterial spores, fungal spores, non-enveloped viruses, and combinations thereof. |
