Liquid washing or cleaning agent containing protease and amylase

A liquid washing or cleaning agent comprising:

• (a) a protein comprising a protease having an amino acid sequence which, over the entire length thereof, is at least 95% identical to the amino acid sequence stated in SEQ ID no. 1 and, in the numbering according to SEQ ID no. 1, has the amino acid substitution R99E or R99D, in combination with the amino acid substitutions S3T, V4I and V199I;
• and
• (b) a protein comprising an amylase which is an α-amylase variant of the α-amylase AA560 having an amino acid sequence which, over the entire length thereof, is at least 95% identical to the amino acid sequence stated in SEQ ID no. 4, and in the numbering according to SEQ ID no. 4, has the sequence modifications R118K, D183* (deletion), G184* (deletion), N195F, R320K, and R458K;
• wherein the protease having the amino acid substitutions exhibits improved cleaning performance after storage as compared to a protease according to SEQ ID no. 1 free of the amino acid substitutions S3T, V4I and V199I after storage, and
• wherein the amylase having the amino acid substitutions exhibits improved cleaning performance after storage with the protease having the amino acid substitutions as compared to after storage with a protease according to SEQ ID no. 1 free of the amino acid substitutions S3T, V4I and V199I.
