Abstract

Method for pickling ferrous surfaces, characterized in that it comprises contacting said surfaces with a composition containing a pickling acid from the group consisting of sulfuric acid and hydrochloric acid, and a small amount of a pyrrole ring compound of the group constituted by pyrrole, pyrrolidine, 1-methylpyrrole, 2,5-dimethylpyrrole, indole, indoline, and 2-methylindol, 2,5-dimethylindole and 3-pyrroline; and washing said ferrous metal to separate the pickling composition.
