A process for the preparation of a product for pickling, deoxidizing and phosphating simultaneously ferrous metals, cold, by simple immersion, characterized by the fact that an aqueous solution of a salt is prepared that releases cations that have an electromotive voltage comprised between -2,400 to 3,320 - taken on the basis of hydrogen tension, that is, in fact, an alkaline salt that is incorporated into that solution and a cationic inhibitor organic product ratio of 0.5 to 2.5%. This solution is mixed with 40 to 60% orthophosphoric acid of 10 to 60º Bº, according to the intended applications, and a catalyst is added to activate its action on the metals to be treated, for example, a sodium nitrate at a ratio of 1 to 4.5% of the total weight of the composition.
