Abstract

In a dishwashing liquid, the cleaning performance, in particular on bleachable stains such as, for example, tea stains, is to be improved. This succeeds using a dishwashing liquid which comprises a hydrogen peroxide source, a bleaching catalyst and a protease that, in native electrophoresis on a polyacrylamide gel, has a migration distance that is longer than the migration distance of the protease as per SEQ ID NO. 1.
