A contact lens cleaner and a method for protein removal and sterilization by electrophoresis dissociation are disclosed. The contact lens cleaner comprises a lens cleaning tank (10), two electrophoresis dissociation probes (20) are arranged in the lens cleaning tank (10) opposite each other, and the electrophoresis dissociation probes (20) are electrically connected to a circuit power supply. The lens cleaning tank (10) is filled with an electrolyte solution; a lens to be cleaned is placed in the lens cleaning tank (10); and a switch is turned on, and the two electrophoresis dissociation probes (20) in the lens cleaning tank (10) form an anode and a cathode. There are lacrimal proteins on the surface of the lens to be cleaned, the lacrimal proteins are charged in the solution, and the charged lacrimal proteins move to the electrode opposite to the electrical property thereof in the cleaning tank (10) according to the phenomenon of electrophoresis. The electrolyte solution reacts chemically in the cleaning tank (10) to produce hypochlorite having a strong oxidizing property, and the hypochlorite can degrade the lacrimal proteins, and also can sterilize and disinfect.

The present disclosure discloses compositions and methods for multipurpose disinfection and sterilization solutions broadly effective against multiple microbial pathogens. The present disclosure demonstrates broad spectrum antimicrobial activity against environmental and pathogenic amoeba, bacterial spores, vegetative bacteria, fungi, rickettsia, viruses, parasites and toxic microbial products. The multipurpose disinfection solutions of the present disclosure may be used alone or in combination for a variety of purposes, including disinfection of medical devices such as contact lenses, contact lens cases, surgical instruments, and dental instruments.

An acidic aqueous composition having a pH of from 1 to 4, for elimination of spores of spore forming bacteria, comprises from 100 to 2000 ppm dissolved chlorine dioxide, and a surfactant system having a 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 and are anionic surfactants at a pH of from 1 to 4, selected from the group consisting of soluble salts of alkyl sulphates, alkyl sulphonates, alkyl aryl sulphonates, and aryl sulphonates, having between 6 and 25 carbon atoms in the alkyl chains. Methods of eliminating spores of spore forming bacteria from the genus Clostridium on a surface comprise contacting the surface with an effective amount of the composition.
