Abstract

A system and method to clean and disinfect hard surfaces such as plaster, drywall, concrete, linoleum, counter tops, wood, metal, tile and the like is disclosed. The system and method use electrolyzed acidic water produced by an electrolysis process using a standard electrolyte solution of water and an electrolyte, wherein the electrolyte includes sodium chloride (NaCl) at a concentration between about 1% and 50%. In a preferred embodiment about a 20% concentration of sodium chloride is used. The electrolyzed acidic water produced by this method is effective in cleaning and disinfecting hard surfaces.

Claims
