A rinse aid composition and method of using it in a machine dishwasher isndescribed. The composition contains a polymer having about 50 wt. % to aboutn99% by weight of an olefinically unsaturated carboxylic acid monomer andnabout 1 wt. % to about 50 wt. % of at least one monomer including ancopolymerizable sulfonated monomer, copolymerizable nonionic monomer ornboth. The composition prevents the formation of scale in the machinendishwasher. |
