Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to clean brass hinges [title] Determine if you have brass-plated metal. [step] 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.

Ending1: If it sticks, you'll know it is not made of solid brass. [substeps] 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. Ending2: 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. Ending3: Wind the magnet over the brass and ground it, crushing the brass. Next, lay your brass hinge side down on a soft-dry towel. Ending4: [substeps] 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.
