Summary:A process for descaling a metallic body, wherein the body is immersed in a first electrolyte, and subsequently, in a second electrolyte. The first electrolyte is an aqueous solution having, by weight, at least 60% potassium hydroxide, at least 5% water and no more than 30% potassium nitrate, and a total amount of potassium hydroxide and potassium nitrate of at least 80%. The second electrolyte is an aqueous solution of at least one neutral salt from the group consisting of the chloride, sulfate and nitrate of an alkali metal or ammonium.
