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).
