No RB I didn't clean the retraction wheel/mechanism since post cleaned seemed to do the trick. I cleaned the belt with very hot water with some added Lysol cleaner and used a brush. I then rinsed and went over again with a rag and and some very mild bleach deluded warm water. Your steam method would certainly be ideal.
