I could take it to the sink to do it and really work at it, but I
couldn't do much for the lower one - and obviously removing the whole

I don't think it's a failure mode I've ever seen mentioned on the list
before. I wonder it's it's one that's going to become more and more

If you can get enough access to it, try a small length of steel wire or
maybe a small nail. It will pick up the magnetic junk that's stuck to the

I've seen this sort of thing in high end VU meters used in the meter
bridges of large studio mixers before. Talk about a huge mess...
Some of the Simpson 260 meter movements had the same sort of problem,
though AFAIK they didn't use rare earth magnets.
