I'm sorry I'm not familiar with Angelina. If it's something sticky by chance? Something that might leave a film when heated? I have used a hot dampened thick terry cloth and very hot iron. Ironed and pressed and pressed when ironing and steaming. Rubbing the spot with several small strokes more ironing and rubbing. If this hasn't cleaned the iron then finally a little toothpaste to polish. I also used Rowenta cleaner which is excellent. Will take just about anything off the bottom of the iron. After I've said all this I hope it will help! I can't wait to find out what angelina is!!
