So I bought a proper pump container that will not breakdown with acetone it's called a PUMP n SPRAY with special 'viton' seals that don't break down. These pump bottles are about $50 each. I bought a quart of cheap ATF and ACETONE, mixed them together 1:1 and they fill up the container entirely. I'm going to use this new formula as my regular penetrating oil. ![]() ![]() ![]() I used my label maker to label the bottle so in case I forget one day Something I found online:

i like the spray bottle although $50 seems a bit stiff, where did you get yours? Looking forward to your report on how efectively this concotion works. |

I tried this concoction a few years ago and didn't have much luck with it. PB Blaster works best for me....

I've got access to tons of Acetone (no really, thousands of gallons) and always wanted to try acetone/atf but never have for some reason. Let us know how it works out for you. |

Turpentine is what you want to mix in. Acetone is no good on rust |

The acetone isn't for the rust, it is for penetration. The ATF is for the rust. |

What is disappointing is on the second day the Acetone completely destroyed the gasket seal on my so-called 'viton' seal pump-n-spray bottle. argh ! |

Hmmm, I'm surprised that the Viton didn't handle it. We catch hell at the plant with Toluene. It eventually eats all the pump seals. |

I did a tremendous amount of research regarding that Test which found the Acetone ATF combination as best. It turns out that the original test DID NOT use Acetone but rather trichlorethylene, a common solvent when we were a much heartier people. Here is a reply by the original author of the test which appeared in homeshopmachinist: (and the link to my penetrant thread click here NOTE: Methyl salicylate (Oil of Wintergreen) is used by the Navy as a penetrant and is probably the best out there. However, I have not found any comparative testing. You have to remember that a penetrant is simply oil. It does not break down the oxide crystals - that must come from some other source. And as far as pistons stuck in bores, there is a "crust" that forms on the piston skirts that causes, literally, an interference fit. You can soak all you want, but if it isn't acid (vinegar) or a chelating agent (Evap-O-Rust) that crust will not disappear and you will not free up the piston.) Why They Don't Mix? ANSWERED! Finally found this, a reply in a thread basically dedicated to the same topic came from the author of the article that appeared in Machinist's Workshop magazine. He said they got tons of inquiries because they don't mix! Here is what he said and was published in a subsequent issue: I get more mail about this one little article than any of the others we have printed. Almost all of the mail relates to the fact that the two ingredients in the homemade penetrant do not mix. The fact that the photo in the magazine shows a container of Power Steering Fluid, while the text refers to Automatic Transmission Fluid, has also spurred more than a few people to call or write. The author was kind enough to write a reply to these questions and it appeared in the February/March 2010 issue of Machinist’s Workshop. The following is Lloyd W. Bender’s reply: The original homemade penetrating oil mixture called for using trichloroethelyne as the solvent. I cannot recommend trichlor for home shop use and definitely not for anything slightly resembling a business. Both PSF and ATF will form emulsions with acetone under mild agitation sufficient to thin the oil enough to penetrate. Upon standing, these will separate. Acetone performs better than the other commonly available organic solvents, such as methanol, but not as well as trichlor.

Hmm, just like the acetone I have access to quite a bit of MethylSal (we've used more than 1300 tons of it so far this year - for the production of suntan lotion). I might have to try some to see what it does... |

I use "electrical cleaner" for a lot of, well, electrical things. It also is a good clothing spot remover. I didn't realize it was also used as anesthetic http://en.wikipedia.org/wiki/Trichloroethylene#Uses The newer version isn't much better - "Animal studies and a study of 99 twins showed there is a "lot of circumstantial evidence" that exposure to tetrachloroethene increases the risk of developing Parkinson's disease ninefold. Larger population studies are planned." Use with adequate ventilation... Or, try ATF, gas, and flame http://forums.sohc4.net/index.php?topic=84354.0

He set it on fire BUT eventually beat the hell out of it with a hammer. Pretty much the way I freed up my last rusty set of pistons (an old air compressor). |
