You can use a slow cooker to take a lot of the effort out of removing paint from small metal objects like hinges, drawer knobs, and cabinet hardware. Simply place the items into the slow cooker, cover with water, and let them soak overnight on high. For really tough, dried-on paint, add a few drops of liquid detergent to the water. Let the items cool to the touch, then give them a scrub with an old toothbrush. The paint should slip right off, leaving you with like-new hardware for your next upgrade.
