I first hand "lathe" heavy build-up off plastic and metal wheels with a 3x40 (or other small flat head) screwdriver. Then I use 91% isopropyl alcohol on Q-tips (not 70% that's 30% water). Hold the head of the screwdriver against the flat surface of a wheel at about 2 o'clock with one hand at a slight upward angle. Turn the wheel with your other hand toward the edge of the screwdriver and watch chunks and shims of the old stuff fly off. Cleaning with the Q-tips in a similar fashion then goes much faster and produces better results. If you want, then shine up metal wheels with a Dremel, but be careful not to use to course an attachment and/or too high of a speed.
