Daily maintenance of pearls
Pearl has always been loved by people for its warmth, elegance and splendor, and is known as the queen of jewelry. The composition of pearl is calcium carbonate containing mechanism, which has poor chemical stability and can be dissolved in acid and alkali. It is not advisable to touch perfume, oil, salt, alcohol, hair cream, vinegar and dirt in daily life. It is even more impossible to contact organic solvents such as banana oil; People sweat a lot in summer, so it is not advisable to wear pearl necklaces. When not in use, wipe it with a soft, slightly wet clean cotton cloth and dry it for storage. Don't use any detergent to clean them. Don't expose or bake in the sun; When collecting, you can't use mothballs, and don't put them in the bank vault for a long time. The hardness of pearls is very low. White pearls that have been worn for a long time will turn yellow and their luster will become worse. They can be bleached with 1%- 1.5% hydrogen peroxide. Be careful not to bleach excessively, otherwise it will lose its luster.
1. Anti-acid corrosion: In order to keep the luster and color of pearls unaffected, contact between pearls and acids, alkalis and chemicals, such as perfume, soap and styling water, should be avoided. Don't wear pearl jewelry when swimming or bathing. So please put on your lovely pearls after makeup.
2. Stay away from the kitchen: there are tiny pores on the surface of the pearl, which is not suitable for it to inhale dirty substances in the air. Pearl absorbs hair gel, perfume and other substances. So don't wear beautiful pearls to send electricity. Be careful in the kitchen. Don't wear beautiful pearls when cooking. Steam and oil fume may penetrate into pearls and turn them yellow.
3. Cashmere cloth to serve: Every time you wear pearls (especially in hot weather), you must wipe them clean before putting them away to keep their luster. It is best to use sheepskin or delicate flannel instead of paper towels, because the friction of some paper towels will wear pearls.
4. Keep away from clear water: Do not wash the pearl necklace with water. Water can enter the pores of beads, which is not only difficult to dry, but also may ferment inside, and the beads may turn green. If you sweat a lot when wearing it, you can wipe it carefully with a soft wet towel and put it back in the jewelry box after drying it naturally. After the pearl turns yellow, it can be remedied in this way: soaking in dilute hydrochloric acid can dissolve the yellowed shell and make the pearl reappear its glittering and charming color. But if the color turns yellow badly, it is difficult to reverse it.
5. Need air: don't put pearls in the safe for a long time, and don't seal them with plastic bags. Pearls need fresh air, so they should be taken out and worn every few months to let them breathe. If pearls are kept in a box for a long time, they will turn yellow easily. Old and yellow? That's what I'm saying. )
6. Avoid exposure: Because pearls contain a certain amount of water, they should be placed in a cool place, avoiding direct sunlight as much as possible, or in an excessively dry place to avoid dehydration.
7. Anti-scratch of hard objects: pearl jewelry should be stored separately to prevent other jewelry from scratching the pearl skin. If you are going to wear a bead chain on your clothes, the texture of your clothes should be soft and slippery. Too rough material may scratch your precious pearls.
8. Store it flat: Do not hang the bead chain for a long time. After a long time, the silk thread will relax and deform, so it should be stored flat.
9. Pearl ring: When removing the pearl ring, grasp the handle or metal part of the ring, and do not use beads as a bearing place to prevent the bearing surface of the pearl from loosening and prevent the dirt on the hand and the grease secreted by the skin from sticking to the beads.
10. Check it regularly, and change the thread after 3 years: the thread is easy to loosen after a long time, 1 ~ 2 years can be checked regularly and replaced; It is best to re-string pearls every three years, depending on the number of times you wear them. The dirt entering the bead hole will produce friction, which will make the nylon thread break, and the broken position is close to the button.
