When not in use at ordinary times, it should be sealed and stored. Can be packed in a small plastic bag, isolated from the air, reduce the chance of oxidation, and keep the ornaments fresh. The best way to maintain silver jewelry is to wear it every day, because human oil can produce a natural and moist luster.

2. Surface coating

Coating a transparent paint film on the surface of jewelry can isolate silver from the outside air. Ordinary wearers can use colorless and transparent nail polish as the coating film on jewelry. This method is particularly simple and does not affect the luster of silver jewelry.

Step 3 keep it dry

Always keep silver jewelry clean and dry, and try not to let silver jewelry come into contact with sulfur-containing chemical gases. Silver is the only metal that oxidizes when used to make jewelry (commonly known as silver rust). Do not use sulfur soap to clean silver jewelry.

Treatment of silver hair and black hair

1, polishing method

This method is better for plain silver head injuries with smooth surface, such as flowerless bracelets and collars. When polishing, you can use silk or toothbrush dipped in a small amount of toothpaste to polish it repeatedly at the place to be polished until the surface of the jewelry is as clean as new, and then wash it with water after polishing. However, this method is not very effective for ordinary carved or carved silver ornaments.

2. Broken aluminum sheet

Put some pieces of broken aluminum under the silver jewelry, and then heat them together in soda solution to remove the black. Because soda is very alkaline and heated, this method cannot be used for silver jewelry with jewelry.

3. Sodium thiosulfate solution

After cleaning with 1% hot fat room solution, soak the silver ornaments with sodium thiosulfate solution (photographic fixing solution, also known as Haibo), and then wipe them with toothbrush or fiber cloth.

4. Wash with concentrated hydrochloric acid

If the black on the jewelry is heavy, it can also be washed with concentrated hydrochloric acid. After washing, it should be washed with clear water immediately. Jewelry inlaid with pearls, malachite and turquoise must not be washed with hydrochloric acid, otherwise it will damage the jewelry!
