Dismantle if it's useless anyway because it's cool looking inside?
I used (way back) to be an electronics repairman. We got that black goo on a lot of stuff (TV's, stereos, you name it).
Things here pick up a bit -- I'm in the country and for one thing heat with wood -- getting cold here. Sometimes smoke comes out, we cook etc. Doesn't mean the insides of my vac systems aren't really clean, the outsides don't matter much.
Could be I'm the only guy on earth doing fusors and deposition with a woodstove in the room -- which I have used to solder SMD with....kind of fun to be a little different.
(my other turbo system is in my bedroom/kitchen) I'm guessing in some industrial situations it's pretty goopy too, though most I've seen are sparkling clean.
Friend John Bain (who I hope will show up here) designs solvent recovery plants, ethanol plants, things like that. They are pretty nasty, and they use vac pumps all the time.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
