Abstract:
1. A method of washing ware comprising: (a) contacting ware in a washing step with an aqueous cleaning composition in a ware washing machine, the aqueous cleaning composition comprising a major portion of an aqueous diluent and about 200 to 5000 parts by weight of a ware washing detergent per each one million parts of the aqueous diluent, wherein the ware washing detergent comprises a nonionic surfactant; and (b) contacting the washed ware in a rinse step with an aqueous rinse, the aqueous rinse being substantially free of an intentionally added rinse agent, characterized in that the aqueous cleaning composition contains a sufficient amount of a cationic starch to provide a layer of the cationic starch on the ware so as to afford sheeting action in the aqueous rinse step, wherein a weight ratio of the nonionic surfactant to the cationic starch in the aqueous cleaning composition is at most 0.25/1, further wherein the cationic starch contains a cationic group which is a quaternary ammonium group according to the formula wherein R further wherein the cationic starch is (3-Chloro-2-Hydroxypropyl)Trimethylammonium Chloride modified starch, and further wherein the ware washing detergent further comprises a defoaming agent or the aqueous cleaning composition further comprises a hydrotrope, wherein the defoaming agent, the hydrotrope and the nonionic surfactant are different compounds.
