Following this thread since I love watching this kind of cleanup.

What did you use to clean the bottom control panel board? I took mine outside and used a Shop-Vac to blow and suck away all the dirt and metal dust. It would have been nice to scrub the wood, but it was too tedious to get in all those nooks and crannies. Mine looks a lot better, but not quite as bright as yours.

I'm also in love now with using the Dremel polishing/cleaning tips for the stepper contacts (and anything else I feel like shining up).

Was your score motor making weird noises? I didn't think they really ever needed to be oiled unless something was acting up.
