Gummed Up Iron?
If you're not using a Goo Grabber with your fusibles, you're going to get glue on your iron. It happens. I've used Iron-Off to clean the sole plates of my irons for years. It works great.
A while back, my friend Chris Porter was teaching on a cruise and one of the irons got gummed up. No Iron-Off. She couldn't think of anything to use to clean her iron except nail polish remover pads. They worked like a dream! Just lay one on the ironing board, then iron over it and presto - the glue disappears. The more basic (cheaper) the nail polish remover pad, the better it works, so forget the stuff with the moisturizer!
