I often hear a saying that "the people are old and yellow". The beads mentioned here are also pearls. When the pearls are worn or placed for a long time, they will turn yellow. How should we clean the pearl necklaces we often wear when they are yellow?
Pearl necklace
To deal with the yellowing of pearls, we must first understand why the pearls are yellow. Pearl has a certain life span, and yellowing is one of the manifestations of pearl aging. After a few decades, the pearl will slowly have a faint plain yellow color and lose the unique luster of the pearl.
Pearl necklace cleaning
1. After the pearl is slightly yellowed, it can be remedied by dilute hydrochloric acid soaking. Soon the pearl is soaked in 1% - 5% dilute hydrochloric acid or hydrogen peroxide. As the foam is produced, the yellow outer shell of the pearl skin is dissolved, and the pearl is quickly taken out, washed with water, dried, and the pearl is replayed. But pay special attention, do not soak in dilute hydrochloric acid for too long, in case the pearl is damaged.
2. For pearl jewelry with blackening, dullness and serious staining, it can also be soaked with 10% salt water, washed with 3% concentrated hydrochloric acid solution, and then rinsed with water to restore luster.
Although the above is a method of cleaning pearls, if the treatment is not correct, it will cause further damage to the pearls. Therefore, it is recommended to go to the jewelry store for professionals to help.
The reason why pearls are yellowed is also partly because of improper maintenance. If the pearls are taken care of, the color will turn yellow in about six or seven decades. Xiaobian will share some pearl maintenance methods.
1. Avoid contact with sour vinegar, alcohol and perfume when wearing. It is not advisable to wear a fabric that is too hard to prevent scratching the skin of the pearl. Before the kitchen, the pearl should be taken off, and the surface of the pearl has fine pores. The adsorption of oil and soot may cause yellowing.
2. When not in use: Before putting it into the jewelry box, don't forget to use a flannel to wipe off the dust, sweat or grease left on the surface of the pearl.
3, no need to clean the water, water can enter the small hole of the bead, not only difficult to dry, may also make the inside fermentation, the bead line may also turn green.
