1. Use a old credit card or something like it, to first scrape what you can off the drum.
2. Blow dryer, heat it up as much you can
3. WD-40 on a cloth, wipe wipe wipe keep it up and wipe some more. Be sure to keep a window open or a fan blowing for ventilation.
4. To finish off. Dish washing liquid. If you still find more do again....
