Abstract

Water-soluble detergents and enzymes are used for mechanically cleaning textiles or crockery. According to the invention, enzymes with a catalytic effect on typical stains are added to the washing or cleaning process, only for as long as their catalytic effect is desired. This avoids superfluous removal of the enzymes that have been used in a washing or cleaning process.
