I learn a long time ago that you should clean them by soaking in Vinegar (distilled) overnight and then clean them in warm water next day, at least every 10 rolls. I have Patterson reels that are 20+ years old (my dad used them) and are still working well, I cleaned them like that once a month. If your reel is too worned out, you may just replace it.
