This situation is because in the process of wearing, people's sweat is sticky, attaching heavy dust in the air and human hair to pearls!

The solution is also simple:

1: Cut the thread of the pearl necklace, clean it and put it back on.

2. Secondary polishing (professional jeweler required)

3. Self-polishing treatment: mutton powder 20% citric acid 65% baking soda 15%, mixed into polishing solution, washed by itself.

Is it solved?
