1. A solid rinse aid composition comprising:
- sodium sulfate;
urea;
water;
sheeting agent comprising one or more alcohol ethoxylates;
defoamer component comprising a polymer compound including one or more ethylene oxide groups; and
one or more additional functional material(s) to form a solid rinse aid composition that has a pH of less than 2.0 or to provide a use solution having a pH less than 4.0 when the solid rinse aid composition is diluted with an aqueous diluent,wherein a combined amount of sodium sulfate and urea is sufficient for solidification of the rinse aid composition.

Abstract
The present invention is a solid rinse aid composition and methods of making and using the same. The solid rinse aid composition generally includes sodium sulfate and urea as solidification agents and an effective amount of an alcohol ethoxylate compound sheeting agent component and an effective amount of defoamer component. The solid rinse aid composition may also incorporate a preservative system including sodium bisulfate. The solid rinse aid composition may be phosphate-free, aminocarboxylate-free, and GRAS if desired.
