1, if you don't wear jewelry for a long time, take it off first (note, if it is fixed as a whole, break it slowly, and be careful not to cause plastic deformation or break it because of excessive movement. Then add detergent and a little white vinegar to warm water, and wash off sweat and dirt with a hard toothbrush or similar brush for about ten minutes. This is the first step.

2. Next, find a box, prepare a soft paper towel or cotton cloth to wipe it and wipe off the water stains on the ornaments. If there is a ditch that is not easy to clean, dry it with a hair dryer or naturally, then wrap it in cotton cloth and put it in a box. Of course, if conditions permit, it is best to use sealed bags for vacuumizing and packaging. At this time, the jewelry will be in a sterile and oxidation-free state, and it will not fade and deform even if it is not worn for a long time.
