Rust penetrating fluid

[bixxjs]

Hi All
Does auto trans oil and acetone really work as a rust penetrating fluid?

 

[Stadger]

Not as good as some but better than others. Yes.

 

[Fixnfly]

Works well for me.

 

[Banjorear]

Works great. Almost as good as Kroil in my experience.

 

[oldmxracer]

Yes it works !

 

[Gizzy]

What's the ratio...1:1 ?

 

[oldmxracer]

50/50 give it time to work!

Kroil is tough to beat if your patient.

Acetone / ATF is about all I use.
No complaints at all, other than it separates. Just give the can a shake before using.
I use the refillable areosol cans from Menards...very happy with them too.

Lots of trans oil weights. What is recommended? Thinner the better?

I didn't believe in the 1:1 acetone:ATF mix to begin with, I decided to mix some up in an oil can and seal it for the time I would need it. The day came when it was a squirrel cage for the AC supply fan where the shaft was frozen onto the cage. Soaked it with the ATF mix and waited a few minutes after failing to get it out normally and saw it really soak into the rusted area. Good few whacks with a 4lb hammer and it popped right out.

Also I give props to my B&D workmate that took those hits really well!

It's all I ever use now.

Yes it works, warming up the rusted part seems to help draw in the mix, Not hot enough to ignite the acetone though.

Huh I'd never considered different grades of TX fluid.
Ive found GM dexron 3 or equivalent to work fine for the penetrating mix

Product called Rust Buster. No waiting forever, best stuff hands down.

Some years ago over on Smokestack, there was a link to a "break loose torque" test of nearly all commercial and non commercial rust penetrating products. The 50/50 ATF/Acetone won handily.

Based on all I have heard, I will be mixing up a batch as soon as my Kroil runs out.

this. If you put it into a refillable WD-40 bottle, people don't ask stupid questions anymore.

I'll try this. I don't share the love for Kroil. I've never found it to work better than PB blaster or anything else.
