1. A dispensing system employing an ion exchange resin regenerated by an acid comprising:
- an inlet for providing a water source to a water conditioning unit, wherein the inlet is in fluid communication with the water conditioning unit;
a water conditioning unit comprising a water treatment component housed within, wherein said water treatment component comprises at least one weak acid and/or strong acid ion exchange resin capable of generating a treated water source by exchanging protons on said resin for dissolved cations including water hardness ions and total dissolved solids in said water source; and
an outlet for providing the treated water source to a water delivery line, wherein the water delivery line is in fluid communication with the water conditioning unit and a blending unit, wherein the blending unit generates and/or dispenses a use solution of a cleaning composition by combining the treated water source with a concentrated cleaning composition,wherein the treated water source meets a defined water specification, and wherein the water specification is a softened, acidic water having a total dissolved solids (TDS) below about 200 ppm, a hardness level of less than about 2 grains and a pH less than about 6.

Abstract
Methods and systems for employing softened acidified water sources from an acid regenerated ion exchange resins are disclosed. Various methods of dispensing and/or using the softened acidic water generated by an acid regenerate-able ion exchange resin are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, including water conditioning agents, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.
