I just got a 1960 Vibroplex but and it looks like it has been through a fire! SEEMS LIKE soot, but it does not wipe off at all and even with gentle soap/water/toothbrush still looks like black goo.Any ideas on what to do? What would be BAD to do, what would be OK? I can try to post pix later.

We had a fire here, it is like nothing I have ever seen to remove.  We ended up using neat engine degreaser that seemed to remove the waxy component which is what makes it so sticky.   But, it is a hellova job.

Another thought is it might be soot if it were used in a railyard/train depot. There is an extra hole drilled in the base, obviously to attach to a desk. The top of the (chrome-plated?) cable lugnuts came shiny with my fingernail "chipping off" the crud, as did the dit contact. But the rest of the dit contact assembly is REALLY hard to get the stuff off, oxidation eating away nickel plating? If it were a FIRE the finger pieces would be toast; they are OK.
This was my (cheap) Christmas present to myself, made in my birth year 1963. I gotta fix this Champion.

Just out of curiosity does the hole go through the ID plate, and cover the serial number?

Nope, this is not your long lost bug!  Smiley

You might try vinegar and salt.  Together, they create a WEAK hydrochloric acid that works very well as a "crud removing agent".  I used this method to even remove the rust out of the gas tank of my rescued 1979 Honda.

YMMV

I've had good luck with "Goo-Gone", which has a fair bit of xylene in it.  The Vibroplexes are mostly metal, not plastic, and organic solvents should be safe.

I cleaned her up, not without much effort. Not the best job in the world, but better than when I got it.

See results at www.k3stx.com and click under MY MORSE CODE KEYS for the 1963 Vibroplex Champion.
