Penetrants-[Nut Busters].

Here is something you gearheads should appreciate:
Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts. 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. The results are as follows;
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.
Better known as Panther "P") PJ :highly_amused:
 
Paul - I've used that ATF/acetone mix ever since I read about it here on BCF several years ago. I think that post was the same you just posted. The mix never fails for me.

One guy said "total bull poop - the acetone evaporates so fast it can't loosen the threads". But of course he never tried it. I think the acetone is *expected* to evaporate after carrying the ATF down into the threads.

Thanks for the reminder.

On the contrary, I've tried it many times. There's still a baby food jar of the stuff (for easy agitation just before application) next to the lathe. Still doesn't work nearly as well as letting it soak in PBB or Kroil for a few weeks.

There is also no way in heck that Liquid Wrench works better than PBB.

However, I will say that I measure "success" in terms of whether the threads come apart before the fastener does; not in how easy it is to turn. I can apply all the torque that is necessary, but it's frustrating to twist things off.
 
:iagree: I've never had Liquid Wrench or WD-40 work very well on really rusted threaded fittings. I've had much better luck with PB Blaster and Kroil, although which is better seems to be a tossup. I'll admit that I've never tried the acetone and ATF mix, but mostly because I have no need for the acetone, as I don't use nail polish. :grin:

For some that might be ok, but if I want to remove a frozen nut, I don't want to wait for a couple weeks! On one restoration, I restored a 75 year old plow, similar to this one and there wasn't a bolt on it that would move without breaking it. You can not buy those original bolts, so they got doused with Panther P***, smacked a couple times with a hammer to shock them and the next day I took the thing apart with very little effort. Two plow shier tapered bolts took a couple days to soak and then they broke loose. All bolt were saved on this pile of rust!
