Abstract
A method and apparatus are provided for receiving a cleaning liquid having a pH in a range between pH6-pH8 and an oxidation reduction potential (ORP) between ±50 mV. The liquid is converted into an anolyte liquid and a catholyte liquid having respective pHs outside of the range between pH6-pH8 and having respective ORPs outside the range between ±50 mV. The anolyte and catholyte liquids are applied to a surface, wherein the anolyte and catholyte liquids are, for example, in a combined state on the surface and substantially neutralize to a pH between pH6-pH8 and an ORP between ±50 mV within one minute of the time at which the anolyte and catholyte liquids are converted.
