Glory, if you're brave, very gentle and very careful, Dougdeacon described a "deep cleaning" process with the Magic Eraser that has worked well for me. I've used this process on cartridges that have build up on the stylus: Slice a very thin tapering length of ME that will be very flexible at the tip. Use this strip of ME to very gently wipe the surface of the diamond and cantilever, as opposed to simply dipping the stylus into the ME material. Work very carefully and gently. The piece I cut that has worked well for me is about 2" long and tapers from about 3/16ths of an inch (where I hold it) down to about 1/32nd of an inch at the working tip. use a magnifying loupe to watch as you work. Just be very careful, slow and gentle as you work if you try this.
