I saw this artical about removing rusty bolts: Using nuts and bolts that were "scientifically rusted" to a uniform degree by soaking in salt water, they then tested the break-out torque required to loosen the nuts. They treated the nuts with a variety of penetrants and measured the torque to loosen them.

Results:
Nothing: 516 lbs
WD-40: 238 lbs
PB Blaster: 214 lbs
Liquid Wrench: 127 lbs
Kano Kroil: 106 lbs
(ATF)/Acetone mix (50/50): 50 lbs.

The "shop Brew" of 50% automatic transmission fluid and 50% acetone seems to beat out the others.

Just wanted to pass this on!

Since acetone evaporates very fast, any suggestions for how to keep it from evaporating out of the mix?

Put it in a bottle with a lid. We have gone through all this in an earlier thread. I've been using the 50/50 mix for some time with very good results.

HMMM, since I have an spare small 3 in 1 oil bottle w/ the pull out plastic tube it would probably work good to keep it in.

Is that not the same stuff that DanO calls "Pony Piss " in his videos?

I don't know about that. I learned about it from an old mechanic years ago.

I read about this here when I first found this place. I mixed up a little to try and it seems to work pretty well.
I label mine, "RUST BUST."

I have something similar, small bottles with pull out spouts and little caps for the end. Just have to shake it good before you use it. One bottle is even labeled 'Rust Buster'.

Makes sense, the acetone offgasses quickly, and cools the part it is on. The surrounding metals shrink, thus letting the relatively thin oil in.
I have used it for a few years , and can tell ya it works well, even though the arnmhair theorists are the only one's to prove it LOL

When I use it on a really rusty bolt, I will usually let it 'work' for quite a bit. Sometimes, I'll put this on and wait til the next day to try to loosen the bolt. If it turns just a little, I'll put a bit more on. They usually come right off. I think I have only broken 2 or 3 of the real rusty ones off using this.

I have also just started hearing from different fellows about the mix, sound good to me and I like the small bottle with the long pull out spout, but you have to remember to place the cap back on or you loose the acetone. I remember using the small bottle when I was doing A/C work, a very handy little bottle.

I use to use Kroil for many years with excellent results. Then I read about the transoil and acetone but was concerned about the evaporation of the acetone. I have noticed over the years that it takes a very little diesel spill for the stuff to creep everywhere. Tried mixing diesel 50/50 with old Auto transmission oil and that seems to work OK. Takes a little longer to penetrate than kroil but so far the results have been favorable.
