Why Does Sterling Silver Tarnish? How to Clean It?

Why Does 925 Sterling Silver Tarnish?
925 sterling silver jewelry can tarnish over time. While many perceive this as a "defective product," it is actually a completely natural and expected process.
925 sterling silver contains 92.5% pure silver and 7.5% other metals, usually copper. Silver, by its nature, reacts with sulfur in the air, and this reaction results in darkening (oxidation) on its surface.
Main causes of tarnishing:
- Air and humidity: Silver reacts faster in humid environments
- Perfumes and cosmetic products: Chemicals accelerate tarnishing
- Perspiration: Skin pH can affect the color of silver
- Water and soap: Constant contact can cause dullness
- Enclosed and airless environment: Jewelry that is not used for a long time can tarnish faster
👉 Important point: Tarnishing does not mean the silver is of poor quality. On the contrary, it is a natural characteristic of real silver.
