1-31. (canceled)
A detergent composition comprising:
- (a) an effective soil removing amount of a nonionic surfactant blend comprising:
- (i) a nonionic surfactant comprising a hydrophobic group and an (EO)x group, wherein x is a number of about 1 to 100;
- and
- (ii) a nonionic silicone surfactant comprising a hydrophobic silicone group and a pendent hydrophilic polyalkylene oxide group;
- (b) an effective amount of a hardness sequestering agent;
- (c) an effective amount of binding agent to provide the detergent composition as a solid;
- and
- (d) wherein the detergent composition includes an effective soil removing amount of a source of alkalinity to provide the detergent composition with a pH of at least 10.0 when provided as a 1 wt. % aqueous solution.
