1. When cleaning silver coins, the soaking time is determined by the degree and amount of corrosion.

2. When soaking, gently wash with a soft brush. Under normal circumstances, stains will be removed.

3. When stubborn stains on silver coins cannot be removed with a soft brush, you can gently remove them along the edge of the outline pattern of silver coins with a wooden cone until they are clean.

4. Don't touch the silver coin with hard objects such as metal and bone, so as not to scratch the surface of the silver coin and reduce the quality.

5. Do not use abrasives such as toothpaste when removing rust, and keep the original patina of silver coins as much as possible. Try not to clean some silver coins that are slightly rusted and do not affect their appearance.
