There are rubber eraser wheels that remove stripes and decals also, but be careful to move them so they don't heat up. A wax and grease remover will take adhesive off safely. Wet it scrape with plastic squeegee then rub with wet rag till gone. If you use heat gun make sure you don't over heat. 3M makes a spray that turns the whole thing into jelly but its messy and you have to clean adhesive afterward anyway.
