Abstract

Liquid cleaning agents and methods for cleaning are provided herein. In one embodiment, the liquid cleaning agent includes at least one liquid enzyme formulation which includes at least one protease and/or at least one amylase. The liquid cleaning agent further includes at least one solid enzyme formulation which includes at least one protease and/or at least one amylase, wherein the solid enzyme formulation is homogeneously suspended in the liquid cleaning agent. In another embodiment, the method includes the step of providing the liquid cleaning agent. The method further includes the step of dosing the liquid cleaning agent into the interior of the dishwasher.

8 . The cleaning agent according to claim 1 , wherein:
the solid enzyme formulation is comprised in a quantity of 0.01 to 5% by weight based on the total weight of the cleaning agent, wherein the solid enzyme formulation has an active enzyme content of 2 to 20% by weight; and/or the liquid enzyme formulation is comprised in a quantity of 0.01 to 8% by weight based on the total weight of the cleaning agent, wherein the liquid enzyme formulation in particular has an active enzyme content of 1 to 6% by weight.

9 . The cleaning agent according to claim 1 , wherein the cleaning agent comprises the liquid enzyme formulation and the solid enzyme formulation in a mass ratio of 10:1 to 1:10.
