If you want to strip paint from metal without the nasty fumes and mess of chemical strippers, just fill a slow cooker with water and set the dial to high. The heat and moisture will soften the paint, and often it will fall off as a single piece.
Some paints will loosen within a couple of hours, but for best results, plan to cook the hardware overnight. If the paint doesn't fall off by itself, scrub lightly with a stiff plastic brush. The paint will harden as it cools, so scrub the hardware as soon as you pull it out of the water.
