"PB Blaster just stinks!
ATF/acetone couldn't keep mixed together, kept separating."

Now here's a report of +ATF+ and acetone that won't mix. I assumed it was
due to some additive(s) in the PSF I had used, but perhaps not.

So please tell me - is there some half-arsed "green" substitute being sold
as acetone, or something? Sort of like the "PF-TSP" (phosphate-free TSP),
which is free of phosphates, but of course, is not TSP by a long shot. Now
that is some truly worthless crap. If you need REAL TSP, get it from an
industrial supply or eBay.. that's where we get it.

Seriously though, has +anyone+ encountered a petroleum-based oil that would
not go into solution in acetone? What the heck is up with the non-mixing
acetone and ATF / PSF?

FYI - here's the low-down on the whole ATF / PSF & acetone debacle:

Home Shop Machinist was the source of the original article. The author
intended to use ATF, but grabbed PSF by mistake.. and apparently, this
wasn't noticed until some time after publication, and replication by
readers.
