Methods of using a cleaner, sanitizer, disinfectant, fungicide, sporicide, chemical sterilizer

A method of sterilizing objects or surfaces which comprises applying to objects or surfaces contaminated with bacterial spores at a 10.sup.6 /ml to 10.sup.7 /ml level a sterilizing effective amount of a composition comprising from about 10% to about 90% by weight of an alkaline water-soluble salt having hydrogen peroxide of crystallization and from about a fraction of a percent to about 30% by weight of a positively charged phase-transfer agent selected from the group consisting of a phosphonium salt, a sulfonium salt, and a quaternary ammonium salt, said composition in aqueous solution forming both a water and lipid soluble phase-transfer ion-pair and said composition being applied for exposure times up to 4 hours at ambient temperature, to result in 100% kill.

The method of destroying and removing biofilms from objects or surfaces which comprises applying to said objects and surfaces contaminated with biofilms, a destroying and removing effective amount of a composition comprising from about 10% to about 90% by weight of an alkaline water-soluble salt having hydrogen peroxide of crystallization and from about a fraction of a percent to about 30% by weight of a positively charged phase-transfer agent selected from the group consisting of a phosphonium salt, a sulfonium salt, and a quaternary ammonium salt, said composition in aqueous solution forming both a water and lipid soluble phase-transfer ion-pair and said composition being applied to said objects or surfaces at a concentration of 0.1% to 20% (W/V) for exposure times of 1 minute to 4 hours at ambient temperatures.

A method of treating objects or surfaces wherein said treatment consists of combined cleaning, sanitizing, disinfecting, sterilizing and effecting sporicidal and fungicidal activity, which method comprises applying to objects or surfaces in need of cleaning, sanitizing, disinfecting, sterilizing, sporicidal activity and fungicidal activity, an effective amount of a composition comprising from about 10% to about 90% by weight of an alkaline water-soluble salt having hydrogen peroxide of crystallization and from about a fraction of a percent to about 30% by weight of a positively charged phase-transfer agent selected from the group consisting of a phosphonium salt, a sulfonium salt, and a quaternary ammonium salt, said composition in aqueous solution forming both a water and lipid soluble phase-transfer ion-pair.
