Pickling is accomplished by means of a pickling solution, usually acidic, in a bath or possibly in a vibratory or mass finishing process. Pickling and descaling are both processes that are used to clean a metal surface. Pickling removes contaminants from the surface of a metal work piece by using chemistry. Mass finishing applications are also used for descaling. Descaling can be accomplished by using chemistry, but is more often accomplished by blasting.
