Before I invested too much time, I¡¯d clean it up enough to power it up and see if it¡¯s worth the effort. You¡¯ll have bring it up slowly on a Variac to reform the power supply caps.
Then I¡¯d soak the crud with rubbing alcohol and hit it again with brushes. Stay away from strong solvents, you don¡¯t know what they will dissolve.
Good luck

I've acquired a 1950s oscilloscope. The exterior is cleaning up nicely with Simple Green and a toothbrush. But the inside is baked-on dust and fluff. Compressed air isn't cutting it. I don't see any paper parts so I'm willing to risk some kind of spray.
What do you think? Old school potentiometer cleaner? Flux remover spray? Automotive carb cleaner?
