A cleaning composition comprises the reaction product of A) a chelating component and B) an acidic component different from the chelating component. The chelating component is selected from the group of methylglycine-N-N-diacetic acid (MGDA), N,N-bis(carboxymethyl)-L-glutamate (GLDA), nitrilotriacetic acid (NTA), hydroxyethylethylenediaminetriacetic acid (HEDTA), ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and mixtures thereof. The chelating component is generally a salt or a partial-salt of the respective acid, e.g. Na 3 .MGDA. The B) acidic component and the A) chelating component are reacted in a molar ratio (B:A) of from about 6:1 to about 1:6 to form the reaction product. The cleaning composition further comprises a surfactant component in addition to the reaction product. The cleaning composition is useful for removing and/or preventing spotting and filming on ware surfaces in a dishwater, such as for removing and/or preventing filming and/or spotting on cookware, bakeware, tableware, dishware, flatware, and/or glassware in an automatic dishwasher (ADW). |
