So it is like plastic. I would plug it in to get it hot and see how much will come off onto scrap fabric first. I would not use a paper product in case it just sticks to the plastic. A Mr. Clean eraser would have to used on a cold iron or it will melt too? I have not used the Dritz iron cleaner but see if that works on non stick irons. As a last resort, I would try a solvent that could remove paint BUT it might also take off the iron non stick surface.
