Abstract
The present invention relates to automatic dishwashing detergent compositions and methods of using compositions comprising halogenated salts, phosphate and/or silicate in conjunction with electrolyzed water in automatic dishwashing appliances comprising an electrochemical cell and/or electrolytic device for treating tableware to improve cleaning, sanitizing and stain removal by controlling hardness, corrosion and dispersancy.
Claims11
A method for cleaning, sanitizing, and/or removing stains from tableware comprising the steps of:
- A) forming an aqueous solution from a solid controlled release automatic dishwashing composition comprising:
- (a) at least about 0.1%, by weight of the composition, of a halogenated salt which is calcium chloride or magnesium chloride;
- (b) a component selected from the group consisting of a builder, suds suppressor, perfume, enzyme, bleach-scavenging agent, a metal-protecting agent, and mixtures thereof;
- (c) a dissolution control material;
- and
- (d) at least one adjunct ingredient;
- wherein said automatic dishwashing composition is free of bleach, and is in the form of a solid controlled release pill or tablet housed in a porous basket;
- B) allowing said aqueous solution to pass into an electrochemical cell and/or electrolytic device during the wash and/or rinse cycle, thereby forming an electrolytic solution comprising halogenated mixed oxidants;
- and
- C) contacting tableware with said electrolytic solution.
