 I would imagine it depends upon what that stain is or what that mark is. Right. Basically, all you have to do is just get a dump towel and wipe it off. That's the best way to do it. The magic eraser sometimes works pretty good. Some of those products will work, but most of the paints now don't need any of that. All you have to do is just wipe it off, mainly if you use the right sheen, and then you're not scratching any of the paint or anything like that.
