Tarnish
Tarnish refers to the discoloration or dulling of metal surfaces caused by a chemical reaction, typically with sulfur compounds in the air. This reaction forms a thin layer of corrosion on the metal, which can alter its appearance and reduce its shine. Tarnish is most commonly seen on metals such as silver, copper, and brass.
