Abstract: The application is directed to an aqueous liquid automatic dishwasher detergent composition containing a dual bleach system. The composition contains a chlorine bleach source and a bromide compound. The bromide compound is insoluble or only sparingly soluble in the aqueous product liquid composition. The chlorine bleach source can be a hypochlorite compound or a chlorine compound that reacts with water to form hypochlorite. In the wash bath at higher temperature and high volume of water the bromide compound dissolves and then reacts with a portion of the hypochlorite to form hypobromite. The active ingredients of the dual bleach system are the remaining unreacted hypochlorite and the hypobromite which provide improved cleaning performance against both proteinaceous and starchy carbohydrate soils. The aqueous liquid compositions are easily pourable and readily dispersed in the wash bath.
