Thanks to all for your help with this. I've tried Mother's and Simichrome (have not found the Endust yet), and both seem to work very well. Alcohol does well on fingerprints, and cleaning off excess polish. I was using cotton wiping cloths (linen) but have found something that works much better. Had an old cotton flannel sheet, so cut some 1" x 3" strips. Work in a little Mother's or Simichrome, and use an all plastic alignment tool to move the strips between the transformers, caps, around screws, etc. I then finish up with a dry piece of flannel, which gets rid of the residue. It's still a great deal of effort, but the results are pretty spectacular. Thanks again for your help.
