Avoid paint strippers by removing paint from old hardware with crockpot of water on high. Can take 2 hours to overnight. Often will fall off as single piece. Works on oil, latex and spray paints-may not remove some clear finishes like lacquer. May stain or contaminate the pot, so use an old one-won't harm non-rusting metals like copper, brass or aluminum. You'll end up with a little rust on steels-may roughen shiny surfaces. Plated metals like chrome that are flaking may cause more flaking.
