How to clean the gold wares: Crescent -shaped cloud dragon pattern gold ornaments unearthed from the Ming Dynasty have been dealt with.
    The surface of the Ming Dynasty gold decoration was black, blue, and brown -brown rust -like rusty, and black rusty was the main part.
    The average thickness of rust objects is about 1.5 mm, and the surface is rough and uneven. After trials, the general mechanical tools cannot be removed. If a powerful mechanical tool is used, it will inevitably cause damage to the utensil itself.
    Therefore, the mechanical tool cannot be used to remove rust.
