Food processing equipment is cleaned with an aqueous detergent composition
wherein the water in the cleaning composition is demineralized. This is
combined with concentrated detergent and applied at an elevated
temperature to the walls of the food processing equipment. The detergent
composition has sufficient sequesterant to remove 100% to 110% of any
calcium or magnesium ions released from soil that is removed from the
surface of the processing equipment, generally an amount effective to
remove from about 10 to about 35 parts per million hardness ions.
