Removing paint from doors. If the paint is still wet, and in this case it is, and it's an oil base. I would simply wipe it off with some paint thinner or mineral spirits. Applying it to a rag and wiping it off. If it's dry, it's paint that's been on there for some time or it's, the entire door is painted and you want to remove all the paint, you can use a stripper, paint stripper. And there's special electronic tools that get into all the crevices and grind all the paint off. If you just have some splatter or something on, say, your door from painting your walls and it splattered on there you can use a small tool to scrape it off perhaps. Try that or use goof off and follow the directions on the can. And I just would wipe all the paint off until it's gone.
