You could also try to run some cotton yarn between the disks with some polish to see if that helps. I think I saw this on one of Muv's videos as a tip for polishing hard to reach places. Think "flossing" between them.
I found some kind of flossers at the drug store - the ends are nylon or what ever and the middle is fuzzy - a drop of cleaner goes a long ways on one of those.
