[GreenKeys] Homemade penetrating oil

[drlegendre .]

That was me. And I used 50/50 power steering fluid (the actual test
compound, from the original article) mixed with acetone. Same thing, they
separated - not miscible.

The PSF I used was cheap, generic stuff, and not labeled as synthetic,
semi-synthetic, para-synthetic, or any such thing. So what the heck is up?

Is there some sort of "environmentally friendly" pseudo-acetone going
around out there? I simply don't know what to make of it..
