How to Clean Antique Brass Ktichen Cabinet Hinges

Brass is an alloy of copper and zinc and is prone to tarnishing. Antique brass hinges are usually protected by a coat of lacquer, which helps them maintain their color and luster. Over time, the coat breaks down, exposing the brass to the damaging effects of air and moisture. Tarnished antique brass hinges can be cleaned and restored at home as long as they are not severely damaged. Damaged brass should be examined, cleaned and repaired by a professional curator.

Allow thinner to remain on the surface of the hinges for the recommended amount of time. Gently remove loosened coating by brushing the toothbrush along the direction of the grain.
