Patent ID: 8876982

Claim:
A method of washing ware using a cleaning composition containing a surfactant, the method comprising: (a) contacting ware in a washing step with an aqueous cleaning composition in an automatic institutional warewashing machine configured so that no carryover of the aqueous cleaning composition from the washing step into a rinse step occurs, the aqueous cleaning composition consisting of a major portion of water and about 200 to 5000 parts by weight of a warewashing detergent per each one million parts of the water; and (b) contacting the washed ware in a rinse step with a potable aqueous rinse, the aqueous rinse being substantially free of an intentionally added rinse agent, wherein the warewashing detergent contains a sufficient amount of a surfactant to provide a layer of the surfactant on the ware so as to afford sheeting action in the potable aqueous rinse step, wherein the method does not comprise a rinse step with a composition comprising an intentionally added rinse agent, further wherein the aqueous cleaning composition from the washing step does not carry over into the rinse step, further wherein the detergent is in the form of a solid, further wherein the detergent consists of the surfactant, at least one builder material, at least one caustic agent, at least one flow control agent, at least one antiscalant, optionally, at least one antifoam, and optionally, at least one bleach, further wherein the surfactant is present in an amount not to exceed 10 wt %, and further wherein the surfactant present in the detergent and the aqueous cleaning composition is selected from the group consisting of a hydrophobically modified polysaccharide, a maleic acid/olefin copolymer, and a maleic acid/olefin copolymer combined with a polypropoxylate.
