1. A method comprising:
- a) receiving on an apparatus a liquid having a pH in a range between pH6-pH8 and an oxidation reduction potential (ORP) between ±
50 mV;
b) converting the liquid into an anolyte liquid and a catholyte liquid with an electrolysis cell on the apparatus, which has an ion exchange membrane, wherein the anolyte liquid and the catholyte liquid have respective pHs outside of the range between pH6-pH8 and have respective ORPs outside the range between ±
50 mV;
c) combining all of the anolyte liquid and all of the catholyte liquid produced by the electrolysis cell to produce a blended anolyte and catholyte liquid without separate storage of the anolyte and catholyte liquids on the apparatus;
d) dispensing substantially all of the blended anolyte and catholyte liquid from the apparatus through a dispenser onto a surface upon conversion by the electrolysis cell without storage on the apparatus; and
e) recovering at least a portion of the blended anolyte and catholyte liquid from the surface after a residence time and placing the blended anolyte and catholyte liquid in a common recovery tank, wherein the blended anolyte and catholyte liquid substantially neutralizes 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 in step b).

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.

15. An apparatus comprising:
-
a source, which receives a liquid having a pH in a range between pH6-pH8 and an oxidation reduction potential (ORP) between ±
50 mV;an electrolysis cell, which comprises an ion exchange membrane and converts the received liquid to an anolyte liquid and a catholyte liquid, which have respective pHs outside of the range between pH6-pH8 and have respective ORPs outside the range between ±
50 mV;a dispenser; a flow path from the electrolysis cell to the dispenser, which is configured to combine all of the anolyte liquid and all of the catholyte liquid produced by the electrolysis cell to produce a blended anolyte and catholyte liquid without separate storage of the anolyte and catholyte liquids on the apparatus between the electrolysis cell and the dispenser, and wherein the flow path is configured to dispense substantially all of the blended anolyte and catholyte liquid from the apparatus through the dispenser upon conversion by the electrolysis cell; a common recovery tank; and a recovery device, which is adapted to recover at least a portion of the anolyte and catholyte liquids from a surface after a residence time on the surface and is coupled to place the liquids in the common recovery tank, wherein the anolyte and catholyte liquids substantially neutralize to a pH between pH6-pH8 and an ORP between ±
