Here is some interesting Info.Tested by a reputable publisher.

I haven't had the need to try it recently but probably will since I have the ingredients in the garage already.


Subject: To loosen a rusted bolt.


To loosen a rusted bolt.

To all my fellow mechanically inclined "Do it yourselfer's". This
interesting tidbit of info crossed my computer screen. I thought that I
would pass it on for your continuing education and reading pleasure.

Just don't forget that acetone is toxic and extremely flammable.

Penetrating Oils:

Machinist's Workshop Mag recently published some information on various
penetrating oils. The magazine reports they tested penetrates for break
out torque on rusted nuts.

They are below, as forwarded by an ex-student and professional
machinist. 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 oils ........... Average torque load to loosen*

No Oil used ................... 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 is a "mix-your-own-brew" -- 50 - 50 automatic
transmission fluid and acetone. Note this "home brew" released bolts
better than any commercial product in this one particular test.

Our local machinist group mixed up a batch and we all now use it with
equally good results. Note also that "Liquid Wrench" is almost as good
as "Kroil" for about 20% of the price.

A 50/50 mix of ATF and Lacquer thinner works equally as well.
