In a process for producing dishwasher detergent in tablet form containing polycarboxylic acids and their salts as builders, alkalinity vehicles, bleaches, tensides and water-repellent finishing agents and, where desired, conventional additives, the solubility at high temperature and the breakage resistance of the tablets is to be improved. This is achieved in that the polycarboxylic acid and its salts are surrounded in a first stage treatment by a liquid phase of tensides and water-repellent finishing agents, whereafter in a second treatment stage the remaining components are added and finally the mixture is pressed into tablet form.
