Electrolyzing is a common method used for metal restoration. This process involves passing an electric current through a solution containing the metal object and a sacrificial electrode. The electrical current causes the metal ions to migrate from the sacrificial electrode to the metal object, effectively restoring its surface.

Electrolyzing is often used to remove rust, tarnish, and other forms of corrosion from metal objects. It can be a highly effective and efficient way to restore the appearance and functionality of metal items. This process is commonly used in the restoration of antique metal pieces, as well as in industrial settings for cleaning and refurbishing metal components.
