They have special technical personnel, reagents, ultrasound cleaning and other equipment for cleaning.
1. Use a small toothbrush to dip some toothpaste, wash the gold jewelry, and then rinse it with water to restore the gloss as new; you must think of a small toothpick with a dead ends, otherwise the more dirty, especially the gold ring, often bring it with the gold ring.

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. By careful observation, rust -like is likely to be in contact with other material contacts in the tomb and other material in the tomb. It is deposited on the surface of the golden device. Due to the high content of the sulfur in the tomb, according to this It must be metal sulfide, such as copper sulfide and silver sulfide. Copper sulfide and silver sulfide are extremely difficult substances. Therefore, it is difficult to remove these sulfides with general acid -alkali or solvent type cleaning agents. The trials, conventional methods, such as pH and complexing agents cannot remove rust. However, sulfides can oxidize the sulfur ions generated in the dissolved reaction into monomatous sulfur under the existence of the existence of oxidants, causing the dissolved balance to destroy, the dissolved reaction continuously goes down, and eventually all dissolve. The is well known that gold is very resistant to corrosion and chemically reacts with other substances. Only the Wangshui with strong corrosive kings can dissolve gold. It was found that the hydrogen peroxide was adopted by the test, and the appropriate additives were added. It can effectively remove rust, and the gold jewelry is unscathed.
