By the way don’t go out and try to buy “None” as it’s hard to find

For those of us who do our own restoration work, here's some interesting comparisons on penetrating oils sent by a friend.

Happy knuckle busting !

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.

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.

 

Hmm, I thought it was something else. But that's good to know. Thanks

 

Kroil is FREE...........

I get it from work LOL!

 

I usually use Kroil, but since I have a gallon of acetone, I'll be trying the homebrew stuff.

Thanks for the info.

 

I had a bunch of kroil from work but im out now and dont work there anymore .. Was pretty good chit !
ill be home brewing some acetone and ATF...

 

Does acetone kill plastic containers? I know it kills rubber so you can't use most readily available pump sprayers. What would you put ATF/Acetone it in to spray it???

 

"Does acetone kill plastic containers? I know it kills rubber so you can't use most readily available pump sprayers. What would you put ATF/Acetone it in to spray it???"

That's a good question. I'm trying to think of any modern spray bottle that doesn't have plastic in it somewhere. Even the pickup tube in most is made of plastic.

 

Interesting, but as an old machinist I'll stick to my favorite Aero Kroil. We all have our favorite cutting oil concotions too. I like sulpher oil.

 

pb blaster works for me

 

Harbor Freight sells a refillable spray can that I think would work.
