Making penetrating fluid from acetone and ATF

Michael Soldan · Feb 11, 2017

I was reading an earlier post about this mixture as a penetrant. How do you mix this, is it a simple 1:1 ratio ?

dlbuck · Feb 11, 2017

That's the ratio I used.

I have been using a similar mixture for years, however I use lacquer thinner rather then acetone.
Although Lacquer thinner is dangerous, Acetone is much more dangerous. It also is much more expensive and evaporates much faster even sealed up in container.
Purpose is to distribute oil/fluid between materials while thinned with paint thinner.
Neither Lacquer or Acetone have lubricating ability, they are just the propellent.

Better to use kero or minersal sprits. You don't need any thing as explosive as acetone or lacquer thinner.

Jiles · Feb 11, 2017

Yes, you are correct I have used both but prefer Lacquer Thinner.
Just have to be more careful and do in a well ventilated area.

Yes--I have tried it, doesn't do the job as well as the mix and is ridiculously priced.

I would think if you got it on painted surfaces the acetone would lift the paint.

I think there is a simple explanation as to why the home brew works better than the expensive bought stuff . It's all down to money , I find I use much more of the homemade fluid than the commercial product , why ? because it's cheap .
Using five times as much has got to have a slightly better result than a few squirts . Maybe it's the frequency of use , I sprayed the frozen solid mudguard nuts and bolts on my FE35 four times a day for a month . They literally fell out , there was no way in the world that I would have used so much if I was paying full price for it .

I will not tell you why it works, or why some say it cant work,I will just say it works great for me. I keep it in a pump oil can, and shake it up before every use. 50/50 mix

Does anybody remember Mechanics Choice? It was red in color too & it worked.

Leave the acetone out and use diesel if you gotta have acetone 1 part ATF 1 Part Diesel 1 part acetone.

All in said and done it no better than a most of the others out there.

Been mixing mine a little thicker, stays on better. Maybe 65/35 ATF/Acetone. I agree with Charles in Aus with on why it works better.

MarkB_MI · Feb 13, 2017

There's only one mixture that works, and that's when you mix oxygen and acetylene in your torch.

The relative performance of rusted fastener looseners is determined primarily by the order in which they are used. The first one that you use may or may not work. After giving up on one and going to another the success rate is higher. By the time you get to the third it will usually work very well.

They work great when you spritz the bolt, slap a wrench on it, and it turns. They don't work worth a hoot when you spritz the bolt, slap a wrench on it, and twist it off.

The reality is that if the bolt turns right after you spritz it, there was no magic involved. That bolt was never stuck in the first place.
