Removing years of bad paint decisions from hinges and door knobs. Easy as water, heat, and baking soda. I actually did this in my old bungalow. Really very easy, butr emember, metal gets hot people.... I may or may not have burned myself.
How to get paint off door hinges: We replaced the doors throughout the house. The previous owner painted the door hinges with latex based paint. The hinge hardware costed about as much as the doors. To save costs, I put the hinges in a potpourri cooker over night. In the morning, the latex paint peeled right off, leaving a shiny, new looking hinge. I would only use a potpourri cooker because potpourri cookers get very warm but not hot.
