Metal working, for example, pre-plated steel parts efficiently sulfuric acid, caustic soda solution before washing to remove the oil, and then soaked in hydrochloric acid; metal before welding, to be painted in the factory weld a little hydrochloric acid production, etc., are using hydrochloric acid to dissolve metal oxide of this nature, in order to remove rust.
