Tarnish is a thin layer of silver sulphide that forms when silver reacts with certain compounds. Why does my silver jewellery tarnish? Here’s three possible reasons…
1. Body chemistry - sweat has sulfur in it.
2. Body products - makeup, sunscreen, lotions and perfume contain alcohol and chemicals.
3. Environmental - chlorine and household cleaners can oxidise silver. Exposure to humidity can also cause tarnish
