Claims27
A method of providing improved cleaning benefits in an automatic dishwashing appliance, said method comprising the steps of:
- (a) providing a substantially sodium ion-free, aqueous ADW detergent composition comprising:
- (i) from about 20% to about 50% of potassium tripolyphosphate, by weight of the composition, that is prepared by in-situ hydrolysis according to the formula:
- (KPO3)3+2 KOH→K5P3O10+H2O;
- and
- (ii) optionally, at least one adjunct ingredient;
- and
- (b) contacting dishware in need of treatment with the ADW detergent composition during at least some portion of the wash and/or rinse cycle.
