The first thing you will want to do is loosen the super glue a little from the metal surface. Take a rag and apply a modest amount of acetone to it. Then, lay it on the problem area, letting it sit for about five or 10 minutes. Do not apply too much acetone; a small amount will do the same measure of work. The key is to loosen the grip of the glue, not actually remove the glue itself. The acetone is simply going to weaken the glue so that it will be more malleable and easier to scrape or hammer loose. more
