Inhibitors are described for acid solutions employed with ferrous metals, such as in pickling or cleaning baths or oil-well acid fracturing. The attack of clean ferrous metal surfaces in contact with acid solutions, such as pickling baths, is inhibited by the use in such baths of unsymmetrical sulfoximines containing at least one long alkyl chain.
