Pure silver is less prone to oxidation and blackening than impure silver. Silver with low purity is particularly prone to blackening, and silver will be oxidized to blacken when it meets sulfur and sulfur oxides.

Everyone's physique is different, and some people have more sulfur in their sweat, which makes silverware black more easily.

And yours is that silver is oxidized by sulfur dioxide in the air because it has been left in the air for too long. If you just wash it with water, it won't have much effect.

But if it turns black, don't worry. There are many ways to clean silver after it turns black.

1. Wipe silver cloth, which is sold in some shops selling silver jewelry.

2. Detergent, the kind that washes dishes at home, is better with warm water.

3. Toothpaste, if cleaned with toothpaste, because it contains abrasives, if it is particularly bright, the surface of silverware will leave tiny scratches.

Baking soda can also be used to clean silverware.

Remember to wrap it in a soft cloth, put it in a sealed bag after cleaning, and keep it for a longer time.
