Polished Brass Finish - (For Internal or External Use)
Our polished brass products are made from solid unlacquered brass. Regular polishing with a good quality metal polish is recommended to maintain the original highly polished finish. However, if the intention is to allow the surface to age through oxidization, no attention needs to be given. Over time the brass will acquire a darker and more aged patina. This finish has been salt tested to 480 hours, which meets grade 5 British Standard.
