The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of warewashing, comprising:
(a) providing an alkaline source in an amount effective to provide a cleaning composition with a pH of at least about 8 and between about 10 and 800 ppm of a water-soluble anion selected from silicate or aluminate capable of becoming an insoluble oxide when reacting with an acid source;
(b) first washing wares with the cleaning composition without rinsing such that water-soluble anions remain on the surface of the wares and the washing step is not repeated;
(c) forming a reaction product on the wares by providing an acid having a pKa of less than about 6 that when contacting the residual cleaning agent on the wares comprised of the water-soluble anion causes the water-soluble anion to become an insoluble oxide;
(d) rinsing the wares with water after the acid rinse step; and
(e) drying the wares after the water rinse.
2. The method of claim 1, wherein the combination of the alkaline cleaning composition and acidic rinse aid causes a reduction of the surface tension on the surface of the wares to reduce spotting.
