A detergent composition comprises a chelating component, a metal citrate, and a metal carbonate. At least one of following two conditions is typically true: X=(2.29*a1)+(2.51*a2)+(2.26*b)+(2.75*c)+(-0.15*a1*b)+(0.26*a2*b)+(1.33*a2*c); and/or Y=(4.00*a1)+(3.76*a2)+(3.70*b)+(3.10*c)+(-4.11*a1*b)+(-1.57*a2*b)+(0.97*a2*c). In the preceding X and Y conditions, 0<X=2.5, 0<Y=3.5, at least one of al and a2 is greater than zero and less than 1.0, 0<b<1.0, 0<c<1.0, and a1+a2+b+c = 1Ø Further, X is the filming performance of the detergent composition and Y is the spotting performance of the detergent composition. a1 is the weight fraction of the chelating component a1), a2 is the weight fraction of the chelating component a2), b is the weight fraction of the metal citrate, and c is the weight fraction of the metal carbonate. The weight fractions are based on the total amount of the chelating component, metal citrate and metal carbonate present in the detergent composition.
