Abstract

Automatic dishwashing detergents are provided in convenient, compact form without chlorine bleaches or phosphate builders. Thus, monopersulfate bleach such as 2KHSO.sub.5.KHSO.sub.4.K.sub.2 SO.sub.4 is used in combination with protease or amylase enzymes and acrylate organic dispersants to provide good cleaning of tableware. Weak builders such as citrate and pH-adjusting agents such as carbonate, bicarbonate and silicate can be present in the composition.
