The aqueous alkaline cleaning agent proposed contains, as its hydroxide constituent, only potassium hydroxide or a mixture of potassium hydroxide and another alkali, the potassium hydroxide content being at least 20 % by wt., calculated as hydroxide, relative to the total amount of hydroxide present in the agent. The agent proposed enables cleaning to be carried out much more economically than with prior art agents. The method according to the invention includes regeneration of the cleaning agent by means of membrane filtration.
