1. A method comprising:

  • providing at least one of an acidic liquid having a positive oxidation reduction potential or an alkaline liquid having a negative oxidation reduction potential;

    dispensing at least one of the acidic liquid or the alkaline liquid to a surface as a dispensed liquid;

    using the dispensed liquid as a working liquid in at least one of a cleaning or sanitizing operation;

    recovering at least a portion of the dispensed liquid from the surface; and

    treating the recovered liquid by applying an electric potential to an electrode, wherein the electric potential is negative if the oxidation reduction potential of the recovered liquid being treated is positive and the electric potential is positive if the oxidation reduction potential of the recovered liquid is negative, so as to generate ions in the recovered liquid that reduce the magnitude of the oxidation reduction potential.
