Pickling is a method for cleaning metal surfaces. It is usually carried out along with pre-tinning. The workpiece is typically immersed in a solution of sulfuric acid or the like to remove oxide films and other coatings from the metal surface. It serves as a pre-treatment or intermediate treatment for processes such as electroplating, enameling, rolling, etc.
