FYI.... if you get color on the shoe (which you will - generlaly means iron is to hot)... a bounce dryer sheet removes it. Just rub the hot iron on it a couple quick times... and it smells good too . Also... an eraser.. from a pencil.... will remove color that gets on the ultra or monokote from iron as well. For example.. red on your iron shoe and you don't know it.. and you switch to white covering.
