Abstract
Improved mechanical dishwasher formulations are provided which are characterized by the use of a random copolyether foam control agent, and wherein the foam control agent imparts the desirable properties of cleaning and defoaming without the concurrent buildup of spots and films on the dishes. The foam control agent is a copolyether having a molecular weight of at least about 2000 and containing random propyleneoxy (and/or butyleneoxy) groups and ethyleneoxy groups. The amount of ethyleneoxy and propyleneoxy or butyleneoxy groups present in the copolyether is selected such that the cloud point of the foam control agent is equal to, or less than, the operating temperature of the mechanical dishwasher.
