- proteases are enzymes that catalyze the hydrolytic cleavage of the peptide bond in proteins and peptides.
- a protease used which shows increased effectiveness in an aqueous alkaline medium, especially since the cleaning agent according to the invention aims to show low alkalinity even in liquid form by the inclusion of an alkaline agent, the pH preferably in the range from 8 to 12, in particular is about 9 to 10. The latter area is therefore the optimum.
- the amount of protease in the cleaning agent according to the invention is at least about 0.3% by weight, in particular at least about 0.7% by weight, based on dry substance or
- Solids content A range between about 0.7 and 4 parts by weight is particularly preferred.
- proteases in the form of a mixture of at least 3, in particular at least 4 different proteases.
- Proteases which have protease activity in the alkaline pH range are used here in particular.
- the cleaning agent according to the invention they are present, in particular, in granular form with high long-term stability.

It is preferred if the amount of surfactant in the cleaning agent according to the invention, based on dry substance, is at least about 0.3% by weight, in particular at least about 0.7% by weight. The range from about 0.7 to 2.5% by weight is considered preferred.
- a surfactant in particular a biodegradable surfactant, preferably also in the form of a mixture of different surfactants. It is preferred if the amount of surfactant in the cleaning agent according to the invention, based on dry substance, is at least about 0.3% by weight, in particular at least about 0.7% by weight. The range from about 0.7 to 2.5% by weight is considered preferred.
- Surfactants are solubilizers that are practically all surface active.

- organic acids described at the outset in connection with the prior art, in particular citric acid, for example in the form of the anhydride in the solid cleaning agent according to the invention.
- the citric anhydride not only has the function of the carbon source, but, in interaction with the preferred alkaline medium sodium hydrogen carbonate / sodium carbonate, leads to dissolving with gas formation, which favors the overall functional sequences of the cleaning agent according to the invention when it is used. It therefore has a effervescent effect, supports the dissolving process of the components of the agent and acoustic feedback and is also an easily usable carbon source for the fat-degrading bacteria.
- enzymes which break down fat, protein and carbohydrates in particular enzymes which break down carbohydrates, preferably cellulase, can be added to the cleaning agent.
