Claim:
1. A caustic-free detergent composition comprising: from about 0.1-15 wt-% of a threshold agent, wherein said threshold agent is an aminocarboxylate; from about 0.1-15 wt-% of a water conditioning polymer; from about 0.1-15 wt-% of a sequestrant; from about 10-60 wt-% of a non-caustic alkalinity source wherein the alkalinity source is a silicate and/or metasilicate; and from about 20-80 wt-% of water, wherein the water conditioning polymer is a polyacrylate, polycarboxylate or polycarboxylic acid, wherein the sequestrant is a condensed phosphate, phosphonate or organic phosphonate, wherein the ratio of the aminocarboxylate to the water conditioning polymer to the sequestrant is in a ratio of from about 1:1:1 to about 5:1:10, wherein the composition is free of alkali metal carbonates, alkali metal hydroxides, and/or mixtures thereof, does not contain surfactants and reduces or eliminates scale build-up on treated surfaces, and wherein a use solution of the composition has a pH less than about 11.5, and wherein the detergent composition provides an effective sanitizing effect at wash temperatures that are not heated above about 140° F. when employed with a sanitizer.
