This is a sure-fire way to get paint off metal. In a pot (don’t use one that you want to cook in again) bring water to a boil and add about a quarter cup of baking soda (do not stir in) drop your piece in and let sit for 15 mins. After the piece cools enough for you to touch, rub off the paint-for hard to reach spots use a soft nylon brush to get off the rest.
