Before we can talk about how to clean brass properly, the question is: Is it really brass? Genuine brass is an alloy of copper and zinc. Since the zinc content varies, brass has a broad colour spectrum, making it difficult to identify it only by its appearance. One trick is to use a magnet! Take a magnet and check whether it sticks to the object. If it does, it’s probably a piece of iron rather than brass.
Typical brass objects include candlesticks, brass wind instruments, lamps, pots, chalices and door handles. No matter what your piece is, cleaning brass will be easy with these tips.
