Acetone/AutoTrans Fluid - Tested to be THE BEST thread penetrating solution going!

I seem to recall reading somewhere that you need to get the old ATF-(don’t remember if it was the Ford or Chevy kind) because the modern stuff didn’t work. Has anyone else heard this?

Be warned the acetone will evaporate out unless it’s kept in an airtight container. My repurposed military lube bottle didn’t keep it for long.

It's also toxic to your liver and can be absorbed through the skin. We used it to clean salt plates in chemistry for nuclear magnetic resonance, but that was in the 1980s.

That is the Dexron II ATF, it works best with the acetone. Most parts stores still carry it and sometimes Walmart. Been using it, along with Kroil and it is a little faster than Kroil on really rusted nuts & bolts.

I've always kept a spray bottle of it in the garage. I do add a few other oils and solvents to the mix. I also use 50/50 atf and synthetic oil as gun lube.

FWIW the best penetrating oil one can use is a DIY homemade mix of 50% acetone and 50% automatic transmission fluid (ATF).

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 mix): Only 50 lbs!

So is Dextrin better than F or does it matter?
