1. A solid rinse aid composition comprising:
- sodium sulfate;
urea;
water;
a sheeting agent comprising one or more alcohol ethoxylates;
a defoamer component comprising a polymer compound including one or more ethylene oxide groups;
sodium bisulfate; and
sorbic acid and benzoic acid;
wherein the total amount of sodium bisulfate and sorbic acid and benzoic acid is sufficient to provide a use solution having a pH less than 4.0 when the solid rinse aid composition is diluted at 10-500 parts of the solid rinse aid composition per million parts of aqueous diluent and a combined amount of sodium sulfate and urea is sufficient for solidification of the rinse aid composition.
