The invention relates to a process for removing salts or water-soluble substances from a nonaqueous, water-miscible scrubbing liquid in gas scrubbers, which comprises feeding water to the scrubbing liquid until an aqueous phase separates out from the scrubbing liquid, and taking off this aqueous phase. The advantages of the process according to the invention are essentially that it circumvents the salting of the scrubbing media by a continuous removal of salts from such scrubbing processes. Alkyl ethers particularly suitable for the process are, for example, the polyethylene glycol dimethyl ethers having a mean molar weight between 200 and 700, preferably 250 to 550. Corresponding compounds are sold, for example, by Hoechst AG (D-65926 Frankfurt am Main) under the trade name Genosorb.
