The present invention provides a method for producing electrolyzed water composition for use in cleaning and disinfecting of an object. The method comprises preparing an electrolyte solution comprising water, at least one carbonate salt selected from: alkali metal carbonate salts, and at least one chloride salt selected from: alkali metal chloride salts and/or alkali earth metal chloride salts. The method further comprises introducing the aqueous electrolyte solution into an electrolytic cell comprising a plurality of boron-doped diamond electrodes. The method further comprises operating a power supply to apply a predetermined voltage to the electrolyte solution to produce an electrolyzed water composition comprising a plurality of active molecular and ionic species with antimicrobial activity.
