The present invention relates to a method for pickling high-chrome ferritic stainless steel, and more specifically, provides a method for pickling a high-chrome ferritic stainless cold-rolled plate, the method comprising: an electrolytic pickling step of subjecting a high-chrome ferritic stainless cold-rolled plate containing 17-26 wt% of chrome to neutral salt electrolytic pickling and sulfuric acid electrolytic pickling; and a mixed acid soaking step of soaking the cold-rolled plate, which has been subjected to the electrolytic pickling step, in a mixed acid solution containing sulfuric acid and hydrofluoric acid, wherein, in the electrolytic pickling step, the amount of applied current is controlled depending on the annealing temperature, and in the mixed acid soaking step, the content of free HF contained in the mixed acid solution and the oxidation-reduction potential (ORP) are controlled depending on steel components.
