Abstract
The present invention is based upon the discovery that high levels of carbonate salts can be formulated with minor concentrations of phosphates (e.g., about 0.1 to 0.3 percent by weight as expressed as (P.sub.2 O.sub.5) together with low levels of a mixture of certain polycarboxylate homopolymers and copolymers (i.e., in combination, a total of about 0.5 to 8.0 percent by weight), and relatively high levels of nonionic surfactants in a dishwashing detergent formulation while providing satisfactory cleaning without unacceptable spotting and filming and without the need to add a chlorinating agent.
