A rinse aid composition and method of using it in a machine dishwasher is described. The composition contains a polymer having about 50 wt. % to about 99% by weight of an olefinically unsaturated carboxylic acid monomer and about 1 wt. % to about 50 wt. % of at least one monomer including a copolymerizable sulfonated monomer, copolymerizable nonionic monomer or both. The composition prevents the formation of scale in the machine dishwasher. |
