Why Brass Tarnishs
Brass does not rust like iron, but it can tarnish. The tarnish is often a mix of copper oxide, copper sulfide, and zinc compounds. Here's the thing — it forms when the metal reacts with moisture, oxygen, and sulfur compounds in the air. Everyday activities such as cleaning with ammonia, using acidic cleaners, or simply exposing the brass to humidity can speed up this process.
