Quote:By golly. I upended it and dunked it into my usual 50/50 ATF/acetone red sauce and set it on the bench. Came back about 30 minutes later and it moved. Applied more sauce with a q-tip and gave it a while longer. It's now moving it's full range, but a little stiffly. More sauce, more wait, then oil, I expect.
Kermit - good stuff isn't it to break down and release dried gummy residue just by soaking it for a spell and not having to apply any torque force?
As tested, the acetone:ATF mix needs the least amount of torque of any tested solvent to 'break free' rusted bolts ... 53 lbs v 238 lbs using WD-40
Since I read the mechanics test on a forum back in 2009 and started spreading the word ... it has been the cat's meow for me and I'm at the bottom of a quart using it for many applications. Examples:
* I had a decapping pin that had frozen threads with BP residue - dipped it in the mix - took a couple of breaths
- twisted the threads with my fingers and it broke loose
* Bought a Fecker scope with frozen gummy threads. Q-Tip applications and slow light continuous twisting and the threads broke loose and now turn freely
* Broke all the plain steel rusted bolts on my duck boat for replacement with stainless steel
* Latest - removed all the aged hard dried grease on the new original diopter sight from the threads and moving parts
I gave a quart to my marine engine service guys that work on motors used only in salt water ... they swear by it
For those that haven't seen the comparative test ...
