Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts with significant results!
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. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.
Happy knuckle busting !

We've been using the ATF-Acetone mix for quite a while now and it seems to work pretty well. However, I like JB's way of picking penetrants the best: Pick the one that smells the best to you. |

I personally like the smell of breakaway the best and works well with a little heat. |

My secret stuff is oil of wintergreen, you can buy it in food co-ops and health food stores and the such. |

I have not tried the ATF-Acetone mix myself but I sent Richard's table to a machinist friend. He called a few minutes ago and said the two components when mixed acted something like oil in water, they didn't really mix. Is there an additional step in getting the two components to become miscible? |

Searcher - yes, it does separate if it sits. We just give the jug a shake or stir and then brush it on the parts with an old paint brush. |

bgoss, I e-mailed my machinist friend your response and he proceeded with the project. At 7:32 tonight I got this e-mail from him regarding use of the Acetone/ATF mix: "I'm a believer".
He had a small job that promised to be one of those that you wished you had never gotten involved with. I don't know whether it was a case where this concoction happened to be the right solution for the right job at the right time or something else but he was pretty happy about the results.
Thanks for responding. |

I prefer good old wd40 for most hard to open nuts or bolts. I personally feel that the 'home brew' of acetone mix also is quite good enough since my partner had made good use of it in his workshop. Also I have been taking info off the internet through site like http://www.automotix.net/autorepair/diy/ which also give good tips on repair work and maintenance. |
