Abstract
Methods of eliminating spores of spore forming bacteria from the genus Clostridium on a surface comprise contacting the surface with an effective amount of an acidic aqueous composition having an acidic pH of from about 1 to about 4 and comprising from about 100 to about 2000 ppm dissolved chlorine dioxide, and a surfactant system having wetting effect and a spore solubilizing effect. The surfactant system comprises at least two hydrocarbon ionic surfactants stable for oxidation at the acidic pH, of which at least two surfactants have a difference in hydrocarbon chain length of at least four carbon atoms.

A method of eliminating spores of spore forming bacteria from the genus Clostridium on a surface, comprising contacting the surface with an effective amount of an acidic aqueous composition having an acidic pH of from about 1 to about 4 and comprising from about 100 to about 2000 ppm dissolved chlorine dioxide, and a surfactant system having a wetting effect and a spore solubilising effect, wherein the surfactant system comprises at least two hydrocarbon ionic surfactants stable for oxidation at the acidic pH and is present in amount of from about 0.01 to about 2% (v/v), and wherein at least two surfactants in the surfactant system have a difference in hydrocarbon chain length of at least four carbon atoms and are amine oxides having alkyl groups with 6 to 18 carbon atoms.
