Abstract
Solid rinse aid compositions, methods of use, and methods of making said composition are disclosed. Rinse aid is provided by a solidification agent, a sheeting agent, a defoamer component, and a polyacrylic acid homopolymer or alkali metal salt thereof forming a solid compositions. Preferred solidification agents include aromatic sulfonates. Preferred sheeting agents include one or more alcohol ethyoxylates. Preferred defoamer components include a polymer compound including one or more ethylene oxide groups. The solid rinse aid compositions are preferably substantially free of sulfate and sulfate-containing compounds.
