If pearl jewelry is worn for a long time, it will lose its luster, peel off and change color if it is not properly maintained. The following should be noted: 1. When wearing pearl jewelry, wipe it with a clean and moist soft cloth to remove the attached dust and dirt. This is because pearls are weak in acid and alkali resistance and cannot withstand the erosion of sweat.

2. Pearl ornaments should not be exposed to the sun to prevent pearls from losing light, discoloration and peeling. 3. When pearl jewelry is not worn, it should be cleaned with weak acidic professional cleaning agent, thoroughly cleaned with clear water, and then wiped with a clean soft cloth. After drying in the shade, put it in a velvet box and store it in a sun-proof and moisture-proof place.

Special note 1. Pearls should not be in contact with sweat and vinegar, because sweat and vinegar are acidic and will corrode carbonate (the main component of pearls). 2. pearls are afraid of wear and can't be mixed with other jewelry. 3. Pearl should not be in contact with perfume, powder and hair gel, because powder, perfume and hair gel are easy to adsorb on the surface of pearl, which makes the pearl gradually lose luster, peel and change color.

4. When exercising and doing heavy work, pearl ornaments should be removed in advance. Don't touch acid and alkali, and then the color of pearls will not look good for a long time, and it will turn yellow slightly ~ the longer it is, the more yellow it will be ~.

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.

10, check regularly, and change the thread after 3 years: the silk thread is easy to loosen after a long time, but 1~2 years can be checked regularly, and it is best to re-string the silk pearl once every 3 years, depending on the number of times it is seen through. 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.

Pearl has always been loved by people for its warmth, elegance and splendor, and is known as the queen of jewelry.

After the yellow shell is dissolved, take out the pearl quickly, wash it with clear water and dry it, and the pearl will regain its luster.

However, special attention should be paid not to soak in dilute hydrochloric acid for too long to prevent pearls from being damaged. Of course, if the color becomes very thick, it is difficult to reverse it.
