Oxidative dehydrogenation catalysts including mixed oxides of Mo, V, Nb, Te, and optionally a promoter may be dissolved in aqueous solutions of oxalic acid. This permits the removal of catalyst and catalyst residues from reactors for the oxidative dehydrogenation of paraffins and particularly ethane.
