Abstract

The invention provides liquid automatic dishwashing detergents (LADDs) that contain a detergent enzyme and have a pH value less than 7.0. Such LADDs can lack phosphate builders, chlorine bleaches, and alkali, each of which is undesirable from the perspective of human and environmental safety. In addition, the invention provides methods for cleaning tableware.
