So it seems that with the variety of fluid choices means you need more than one parts cleaner?
This is only asked half in jest!
What would be the two most useful solutions?

A retired friend had a petroleum solvent parts washer for years (decades, used Stoddard here, retired to WA, not sure what's in it now).
A few years ago he cut a rounded hatch into the side of a 55 gallon poly drum and installed some sort of pump for circulation (I think it pulls from the middle and shoots it up from the bottom through a tube with holes in it).
It's laid on its' side with the hole up and is loaded with a strong mixture of purple power.
Last I saw he was using it to clean air cooled VW case halves.
He loved it as all he had to do was strip the engine into small enough pieces that you could fit in there.
He cleaned the easily removable stuff off first and wiped out the case, mostly to preserve the mixture.
He showed me a case he had done, and another he had paid a shop to do, his looked better.
