Abstract: The invention relates to a cleanser concentrate having the following composition: 0.5-8.0% by weight of at least one C.sub.5 -C.sub.12 -alkyl sulphate salt, 4.0-15.0% by weight of at least one formulation aid, 4.0-10% by weight of at least one alkanolamine, and at least one commercially conventional proteolytic enzyme in an amount of 0.005-0.1 Anson and, if appropriate, conventional acids or bases for pH adjustment, conventional complexing agents and conventional preservatives, remainder, to 100% by weight, water. A process for cleaning surgical instruments has the following steps: applying a 0.5-100% strength aqueous solution of a cleanser concentrate according to one of claims 1-6 which has a pH of 8-9, allowing the solution to act at a temperature of room temperature to 55.degree. C. for a period of 2 s-20 min, rinsing, thermal disinfection, if appropriate.

Abstract: A process for removing especially starch-containing impurities from crockery in dishwashers makes it possible effectively to remove the impurities if a concentrated aqueous tenside solution is used which contains 0.08 to 2.0 % wt, N-C.sub.8 to C.sub.12 alkyl pyrrolidone, 0.005 to 0.125 Artson units of one or more proteases and/or 0.1 to 6 kilo-novo units or one or more amylases per liter of solution, buffer substances active in the pH range from 5 to 9 and conventional solvent agents and possibly conventional additives like foam suppressors, perfumes, colorants, thickening agents, preserving agents and hardness dispersants.
