Undercoating was the thing back in the 60-70s or so it would seem. I spent hours, weeks, months removing that nasty oil based product off the underside of my 65 I was restoring. This car got a bumper to bumper treatment of that stuff.
We had a dry ice cleaning portable machine setup at work, it would remove grease, paint, plastic coatings on wires, lacquer off of the plastic line-work chains and anything else that got in its way.
I think ours was an industrial unit, we just bought the dry ice by the pound & it came in a refrigerated icebox.
One great thing......no media mess to clean up. The dry ice just evaporates and disappears. Be careful breathing the C02 when the dry ice evaporates. When your lungs get full of 50% C02, you'll go unconscious.
The manufacturing company I retired from used dry ice cleaning many many times on used machines prior to rebuilding. It worked great. Very minimal clean up. We contracted the work. They did it in our parking lot in the summer time. Inside a storage building in the winter time. If the work included powder coat afterwards we would then sand blast. Powder loves a sand blasted surface.
