Bright dip is a chemical process that removes oxides and enhances the brightness of base metals while at the same time providing a shiny finish to the original base material color. The finished-part brightness is dependent on the type of base material.
In addition, the bright dip process does not leave any type of deposit on the surface of the part that might interfere with later processing steps.
The parts are first cleaned to remove the oil and dirt that may be on them from processing and manufacturing. After the parts are cleaned, the parts are then processed with the acid-based chromate conversion coating. The film that forms adds shelf life and prolongs future tarnish and corrosion to the base material.
