How to Clean the Tarnish From a Brass Fixture

Brass is the traditional metal of choice for many fixtures around the home from door pulls to ceiling fans. Tarnish develops on brass darkening and dulling the finish over time. The tarnish is a result of exposure to oxygen and build-up of dirt and grime affecting the top thin layers of metal. Brass is cleaned and polished to a deep, bright finish with only a small amount of effort, and cleansers readily available in the house. A coating of lacquer is applied to some brass fixtures to retard tarnishing. Fixtures with a lacquer coating are cleaned and polished differently than those that are un-lacquered.
