Patent ID: 8603392

Claim:
A method for cleaning using a corrosion-inhibited hypochlorous stream from an electrochemical cell comprising: adding a corrosion inhibitor to an electrochemical cell or to an effluent stream of an electrochemical cell to generate a corrosion-inhibited hypochlorous concentrate or use solution, wherein said corrosion inhibitor concentration is from about 25 ppm to about 3000 ppm, and wherein said corrosion inhibitor comprises a non-oxidizing water soluble calcium salt and a corrosion inhibitor selected from the group consisting of a water soluble, non-thickening polymeric salt having a molecular weight less than about 10,000, a water soluble zinc salt, and a sugar acid; and contacting a surface with said corrosion inhibitor concentrate or use solution, wherein said composition inhibits the corrosion of said surface in the presence of said hypochlorous source.
