Penetrating Oils Compared
Machinist's Workshop magazine actually tested penetrates for break out torque on rusted nuts. Significant results! They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment.
Penetrating oil ..... Average load
None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ..............214 pounds
Liquid Wrench ...... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix... 53 pounds
The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone.
Note the "home brew" was better than any commercial product in this one particular test. A local machinist group mixed up a batch and all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.

Re: Penetrating Oils Compared
Wow who would've thought about acetone, we use it to get black marks & scuffs/small scratches off of white vinyl products. Thanks for the info I'm gonna have to change the u bolts & shackles on my work trailer & will try it then.

Re: Penetrating Oils Compared
Acetone evaporates really fast so how does it do when mixed???
I also here that the d.e.p. is going to get that stuff off the shelf soon so stock up while you can.......

Re: Penetrating Oils Compared
Probably not very scientific. In the shop for 36 years I've found in my not so scientific study that a mixture of oxygen and acetylene works better than all of those if applied correctly. As far as the penetrants go Aero-Kroil is seriously hard to beat. We tried it years ago and it's called "Magic Oil" in my shop. I tried every name brand and not so name brand penetrating oil out there and it works very good. I've never tried the atf/acetone mix even though back when I first opened my shop I used an atf/kerosene mix which worked pretty good but is also pretty stinky.John_Heard wrote:FYI - Might be handy...
