Abstract:
The present invention relates to compositions including threshold agents, and methods of use thereof. The threshold agents can include hydroxycarboxylate compounds present at an amount sufficient to control water hardness. The threshold agents are present in the wash solution at a molar amount less than the molar amount of water hardness ions present.
