Yes, I used it to clean up my 401, which apparently had been stored, face down in the cabinet, in an un-airconditioned area for a long time. The old oil had run to the front of the machine and turned to varnish.
Either Macybaby or Cari-in-oly said to use alcohol, and I did. It worked easier/faster than kerosene. Denatured alcohol works best, but is fairly expensive at Home Depot. I bought some 90% rubbing alcohol at WM, and it works almost as well at about 1/3 the price. It evaporates quickly and doesn't leave a residue.
