Hmm....I wonder if ATF alone would work better than the other products? I am guessing that the acetone is more of a carrying-penetrating agent and the ATF with its detergent properties actually breaks the rust?

I have always favored PB for corroded hardware. For me, nothing else has matched it. That said, I have never tried the 50//50 ATF to acetone mix and I definitely will.
I trust the results, but I wish it included data with regard for how much time was allowed for the penetrating oils to work. My experience has shown me that patience is the key with PB. I can easily remove 928 water pumps without ever breaking one bolt if I soak the hardware in PB at least 24 hours before returning to the vehicle. Just my experience.
It amazes me just how few people, locally, realize the difference in WD40 and others. WD40 has other values that other products don't. I keep both WD40 and PB blaster in my shop at all times.

I have used the 50/50 atf/acetone mix ever since I read Wally's post about it (and I also use PB when I need an aerosol's convenience) and it works as advertised.

Iv'e bought a couple of these but haven't had a chance to use it yet.
Claims to freeze down to -40C to open up cracks in the corrosion
allowing penetrating oil to infiltrate.
Seems logical.

Wally P has been talking about this for years.... I haven't tried the acetone/atf mix yet, but the kroil we have around the shop works way better than anything else so far...

For All of you Mechanic's and Self doer’s out there.
This was in one of the Military Vehicle Club newsletters.
Penetrating Oils
Recently “Machinist Workshop Magazine” did a test on penetrating oils. Using nuts and bolts that they ‘scientifically rusted’ to a uniform degree by soaking in salt water, they then tested the break-out torque required to loosen the nuts. They treated the nuts with a variety of penetrants and measured the torque required to loosen them.
This is what they came up with:
Nothing: 516 lbs
WD-40: 238 lbs;
PB Blaster: 214 lbs;
Liquid Wrench: 127 lbs,
Kano Kroil: 106 lbs
(ATF)/Acetone mix (50/50): 50 lbs.
This last “shop brew” of 50% automatic transmission fluid and 50% acetone appears to beat out the commercially prepared products costing far more.

Great stuff and it's inexpensive.

Guess if it gets rid of that finger nail crap it ought to help in unseizing bolts as well. Interesting suggestion by the way- I'll remember that one!

Not all nail polish removers contain acetone, and those that do often have other ingredients and/or are diluted. Then the cost is several orders of magnitude higher than acetone from a hardware store.

Acetone is a LOT cheaper than nail polish remover. Most current nail polish removers have "other stuff" added to make a gel that doesn't fall off so quick and doesn't run onto skin. Exactly the wrong traits you'd look for in a penetrating lubricant.
I keep a pump oiler on the side of the toolbox with ATF in it. When I need a penetrant, I add some acetone, mix and use. The acetone fractions out and evaporates in a few days, leaving the ATF. FWIW, that squirter pump oiler has been hanging there on the toolbox for 30+ years, used previously to top up the piston dampers in SU carburetors and the imitators. Easy repurposing of a great tool.
