Rusting occurs when water finds its way onto a metal surface and is left alone for an extended period, so oxidation occurs.

One option is to throw out the rusted metal and purchase a replacement, but what happens when that is not possible? Rather than toss out your rusty pieces, learn how to clean rust off metal surfaces. Even if you are careful, metal rusts at some point.
