Abstract

The aim is to improve detergency, in particular on custard stains, in an essentially solid dishwashing detergent. This is accomplished with an essentially solid dishwashing detergent which comprises a protease which comprises an amino acid sequence which is at least 80% identical to the amino acid sequence given in SEQ ID NO. 1 and which has the amino acid glutamic acid (E) or aspartic acid (D) at position 99 in the count according to SEQ ID NO. 1.
