I was searching for info on Kroil and how penetrating oil works to lift the fouling up from the barrel surface. Here's a couple of posts I hope y'all find useful.

Homemade penetrating oil
A while back someone posted the results of test on various brands of penetrating oil. The test also included a home made batch made up of transmission fluid and something else I can't remember. Maybe acetone. It was rated very high. I've tried the search function on the boards I frequent and can't find it. Anybody remember the recipe? I'm about to run out of Kroil. Thanks

Re: Homemade penetrating oil
It looks like the original article was in the April/May 2007 issue of Machinists Workshop.
Quote:
Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results! They are below, as forwarded by an ex-student and professional machinist, Bud Baker.
Don't forget the April 2007 "Machinist's Workshop" magazine comparison
test.
*They arranged a subjective test of all the popular penetrants 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. Our local machinist group mixed up a batch and we 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.
The results have been widely quoted on the internet, but the picture in the magazine allegedly shows power steering fluid and not ATF, and according to lbender (who claims to be the author) in this thread, it actually was power steering fluid (mixed with acetone) that they tested with. Lbender begins participating in the thread on its second page.
