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


There are only two ways that evporating acetone (or any other liquid) will cool the metal. One is if the acetone is compressed and evaporates when uncompressed, much like coolant in an air conditioning system. The other way is if the metal is heated above ambiant temperature. In this case the evaporation of the acetone isn't really what is cooling the metal, rather the acetone is absorbing the heat, much like quinching hot metal in a bucket of water. Some of the acetone may evaporate during this process if it is heated enough.

You may be thinking about how evaporating perspiration cools your body. It does indeed cool your body IF the ambient temperature is below your body temperature.

The reason this stuff works is that the acetone lowers the surface tension of the atf allowing it to work it's way into very tight spaces. The acetone then evporates and leaves the lubricating properties of the atf in place.

Yes , I omitted the part about heating metals to well above ambient temp, sorry about that . Similar quenching can be had with spraying water on a hot part, but with no added lubrocity... And good point about lowering the viscosity with the acetone as well. Thanks :-)

I used to use Kroil, but have went to using Marvel Mystery Oil and have never looked back.
Started using Kroil to clean my target rifle, but a friend was using MMO & Benchrest 9 mixed. He found that it would not change point of impact first round out of a clean barrel. I tried it and he was right. So have been using the mix in my rifle and straight MMO in the shop. It is much less expensive than the Kroil and available anywhere(not the case with Kroil).

Funny you mention the Marvel mystery oil. If I can't lay my hands on the normal penetrating oil I will use the Marvel air tool oil and the results have been favorable. So that's an option also.

The tines on my Cub Cadet #1 tiller are a good candidate for this. One side came off of the tiller shaft very easily, but the other side.... no go, so far. They appear to have grown onto the shaft. I've heated and soaked with PB Blaster several time to no avail. I'm going to give the ATF/acteone mix a try, maybe the Marvel Mystery Oil.

So what would be in ATF that would be better than making the mix with 20wt motor oil for example? I'm not too familiar with the ingredients in ATF.

And since I've only got MEK at the moment, that should also replace acetone fairly well? (Wifey won't give up ANY of her nail polish remover!:D)

Never tried it myself Harold, but as ya know, I'll give anything a whirl.

Hey, watch this! Hold my beer! LOL

Metyl Ethyl Keytone is nasty suff, so it sure might work ....

MEK is highly flammable, even just the fumes in a dry rag can ignite fairly easily. I don't know what is in the acetone, but when it's put on a rusty bolt (w/ATF) I can see tiny bubbles at work. I have used the mix with good results many times.

As far as a handy container for dispensing the HMP oil.  I use a ketchup or mustard bottle that I got at Goodwill for little $.  :thumbs:   Its large enough to hold an ample supply for many projects , has a handy sized nozzle to direct it rite on the target object and it has its own little lid that is connected to it so you don't have to worry about misplacing it /forgetting where you put it.  Just replace the lid after use keeps the solution from evaporating.  Just shake it before each squirt.  :wave:

I've found that melting a candle into the threads is great at loosening rusted bolts.
