If it is just stained, it can be cleaned. If it is rusty, the rust has to be removed and it has to be replated. A lot of the brown discoloration on plating is dried oil that is oxidized. It can be removed with automotive chrome polish. We call it chrome plating however it is actually nickel plating on the older machines. This is very soft and can be damaged further with any harsh abrasive such as Comet. The best way to clean that oil off is to put some mineral spirits or paint thinner on a cloth and scrub it off. You can soak it for a few minutes and then rub it off.
