Thought it might be useful for someone. Dont know if these products are available outside the Antipodes but it might give you ideas. Pat. Machinist's Workshop MagT recently published some information on various penetrating oils Some of you might appreciate this. 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 "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note this "home brew" released bolts better than any commercial product in this one particular test. ________________________________ Message 2 _____________________________________ Time: 07:25:37 PM PST US From: Charlie England Subject: Re: Kolb-List: penetrating oils On 11/18/2012 04:01 AM, Pat Ladd wrote: > Hi All, > this from a mate in NZ.

I can testify; it works.
