Acetone/ATF Penetrating Oil

This message is a reply to an archived post by JerryMT on August 27, 2013 at 20:54:53.
The original subject was "AcetoneATF Penetrating Oil".

I saw a research study done that showed what various penetrants worked the best based on torque needed to break the bolt free. This was from the Machinist's Workshop Magazine and the results were: no penetrant 516 lb, wd-40 238, pb blaster 214, liquid wrench 127, kano kroil 106 and atf/acetone 53 lbs.
 
I tried Acetone/ATF and it seperates and had to be shook every time I used it. So I use Diesel/ATF, that works great. Has anyone else had this problem?
 
must be more to it than that? that must be the turning force after broke free? would need to know the bolt size and what it was torqued to, i would think. cant see a penetrant reducing torque value on a torqued bolt, to break it. i must be missing something.
 
The pounds listed were how much torque it took after the penetrant was used to break loose the bolt. When no penetrant was used it took 536 foot lbs to turning force to loosen the bolts.
 
I do not think anyone who makes a post about this supposed email has actually read the original article! ATF and acetone do not mix. One is polar and the other is not. Like oil and water.

There was no ATF, no bolts, no nuts, no breakout torque, no scientifically bolts. The test was for 24 hours of rusting and only 3 samples of each penetrant. Basically a meaningless "study".
 
I don't know. I wasn't there but a lot of folks do use a mixture of acetone and ATF. Some folks use another type of thinner like
turpentine or other mineral spirits. You might want to read some of the testimonials in YT and tell them they don't know what they are
talking about.
 

My comment was base on the first post in this message. I have the original article. It did not specifically test the effectiveness of acetone/atf.

However acetone and atf do not mix. How effective that combination is or would be as a rust penetrant was not at all my point. My point is that the study used to support the effectiveness of the acetone/atf mix is typically misquoted. There was no breakout torque, no nuts or bolts and no scientifically rusted nuts or bolts. There was no atf/acetone mix even tested. Acetone/atf may be the best rust penetrant in the world but it was never tested in that study!
 
I only reported what I read and made that clear. I don't know and made that clear. It would seem to me that whether or not the molecules
mix does not necessarily determine how effective the penetrant can be used when applied simultaneously. You seemed to be saying there is no
value in using a combination of the two and you may be right. What do you use? You may be able to enlighten all of us. By the way, please
reference the article in question for all of our benefit. thanks.
 
I just use Kroil or Silikroil. Supposed to kreep into a millionth of an inch. It's what we used in the refineries and powerhouses to break rusted flange bolts loose. Works...
 

This topic is on the every 14 months schedule, and ever since it was first posted around ten years ago, every other month when the "best penetrating oil" thread comes up, half of the posters swear by it. I will admit to mixing up a batch in one of my oil squirt cans once, and I gave it a try, but it didn't work any better than anything else. It is a pain to put the two together in a can and it is a pain to keep shaking it up. So I am convinced that only two regulars on here actually use it, and the rest just like to jump on the band wagon.
 

Here is a link to it .

My concern was the use of a ''scientifically rusted environment'',
Anything ' Scientifically ' induced would have a difficult time replicating 40 years of mud ,blood and bulldust rusting on the bolts to my Fergusons .
That said I use it , but substitute thinners for the acetone . Our ATF must differ , the sort I use stays mixed for ages .

The original subject was "AcetoneATF Penetrating Oil".

The original article is from "Machinist's Workshop" April/May 2007, volume 20 number 2 page 35. The original author made some corrections later on.

What do I use? Doesn't matter. I just wanted folks to make a decision based on acurate information, not on a many times repost of an inaccurate recount of a "study". I am not trying to push one penetrant over another, people should be able to make their own decisions.

The study itself is so flawed that is is basically useless but if you read the originl article you will see that there was no breakout torque, no rusted bolts, no atf, and no scientifically rusted enviroment. The rusting method used is for accelerating surface rusting on sheet metal.
 
Please reference the article as I would like to read it. You can tell us what you use surely. Your goal is for all of us to be informed.
Another opinion perhaps gives us another option. Thanks

I would have to see it to believe it... I have used it all and still waiting for one of them to perform magic. I still hit bolts, nuts etc with what I have on hand 99% of the time I find no magic but still looking for it to happen. I have not gave up nor has anyone else cuzz it all still sales :lol:
