How to clean brass hinges
Determine if you have brass-plated metal.
There are two kinds of brass hinges: solid brass hinges, and hinges made of brass-plated steel, zinc, or cast iron. Place a magnet next to the brass hinge you're interested in cleaning.

Possible answers: A). If it sticks, you'll know it is not made of solid brass. If the brass hinge you're interested in cleaning is made of brass-plated zinc, cast iron, or steel, clean it very gently or the brass coating might come off. B). If you've chosen solid brass hinges, you can remove the brass sheets and other components from the hinges. Contact your local hardware store to inquire about access to brass fittings. C). Wind the magnet over the brass and ground it, crushing the brass. Next, lay your brass hinge side down on a soft-dry towel. D). Solid brass hinges are much heavier, and must be stored in the same place for 48 hours before you begin the cleaning process. Use iron-plated brass hinges only if you want to make sure there are no strong connections between the brass hinge and the metal linings.
