For whatever it's worth

Not sure if this has been posted before.Nor did I check it out for validity. I found it interesting and,if accurate, it should be helpful to Hambers.

Good info, I've never heard of the ATF/Acetone mix.

 

I wonder how large the nut was that it could sustain 516 pounds of force and not break the rusted bolt







It had to be HUGE

 

I'd like to know more about this study. I'm going to look this up.

Edit: More info on Garage Journal.

Still looking for the article online.

 

Just added that to the "recipes" on the metal door in the shop!
Going to give that a spin...har-har...spin!

 

I know that trans fluid is a great grease cleaner and I have done better with trans fluid for stuck engines than anything else . Might have to try that acetone mix and see what happens .
As for no being on the shelf to buy , I am sure the EPA would have a ball with us spraying a mix of acetone & ATF all over a rusted nut or something ! I bet there are some more good mixes like that out there but the EPA sure wouldn't like us using it ! The companies have to follow certain tests & standards before they can put it on the market . That is why all the good stuff isn't around anymore to use !
Remember it has to be good for the environment now !

Ha, very true, but it could have been someone my age that made the test. Everything I do seems like it takes 500lbs of force!

 

It could be inch pounds and not foot pounds.

 

I'd like to know how they figured the "scientifically rusted environment" they used all required the same torque to remove dry. if it wasn't the same then the tests are useless.

 

Sounds like bull. This "scientific" rusted bolt does not relate to the real world. none of the professors tests are real world.

Liquid wrench at the near top??? yea right.

 

Acetone, avoid this stuff like the plaque unless you absolutely have to. I was poisened by this stuff as a teenager. Hospitalized, and abdomanal pain like you will never know, it absorbed through my skin. The kinda thing you never forget.
