Acetone and tranny fluid !!

[Bday]

Thought I'd mention to the guys that didn't know about this mixture. I found it on another tractor forum. The guy's there tested all market sold rust busters, and said the mixture of 50/50 acetone tranny fluid beat everything hands down. Every time I use it on rusted bolts and fixtures it proves to work great. We tore an IH wide front down today. The axle tubes wouldn't budge. We heated and hammered, they would not budge. Soaked them with this mixture in 6 hrs could slide them out by hand. Try it. It works!!!

remember to agitate often!

I realize that most members adhere to safe measures when working with chemicals, but I wish to insert this warning. I once worked at a major boat manufacturer in Acetone Recovery. Acetone is highly volatile and is a flash explosive.

Good information - thanks, creekbend.

Thanks for the recipe. I may well try it next time i need to unstuck something rusty if my usual Kroil or brake fluid don't do the job.

The OP formula is a variation of Ed's Red bore cleaner used for gun cleaning. A penetrating oil test by Machinist Workshop magazine had the following results for removing rusted identical nuts in a scientific environment..

Penetrating oil ..... Average load

None ...................... 516 pounds
WD-40 ................... 238 pounds
PB Blaster .............. 214 pounds
Liquid Wrench ...... 127 pounds
Kano Kroil ............. 106 pounds
ATF-Acetone mix....53 pounds

The tranny fluid must affect the flashpoint of the acetone. We were and have use rose buds around the mixture. As with anything flammable I wouldn't recommend using heat around an open can or large amount of the stuff! Mixture appears to boil more than ignite when exposed to flame,but I'm not trying to get any flame around a large amount! Common sense must be applied!!!!

Acetone had a boiling point of around 150degreesF. The gas given off is highly combustible..

Both of those ingredients will burn although the Tranny fluid is much higher temp for ignition. Maybe the acetone was burning with an almost invisible flame that you didnt see. I use my used motor oil and hydraulic oil to burn brush piles with and it is a good fire starter.
Try your 50/50 mix in the dark and see if it burns.

Yeah, those msds sheets are for chickens and osha! Neither have any common sence.

most of the time you add oil to something like gas.. you raise the octane.. thus the flashpoint.

Actually, the higher the octane, the higher the flash point

you do realize you just agreed with me don't you?

high octane.. high flashpoint.

that's EXACTLY what I said...

Octane is an index of a fuels RESISTANCE to volitilization. You may have been thinking of CETANE number which is more volatile as the number goes up.

Also liquids are LESS volitile as flash point goes UP. Acetone has a flash point of NEGATIVE 20C. That means it can burn when that cold.

I've been using the 50/50 mix since I heard about it on a certain (unique) car forum...probably 7-8 years ago...

I keep the mixture in a mason jar with a good seal and pour it into a pumping oil can when I'm working on something requiring it...if your container does not seal completely the acetone will evaporate away over time....

Great minds think alike I guess

re-read my post.. AGAIN.

the higher the octane.. tha 'harder' it is to ignite and burn that 'fuel'.

ie.. both #'s go up.

I know what cetane is and that's why i didn't mention it.

Yes, but gasoline dissolves oil forming a solution. Acetone OTOH, forms a suspension with ATF. You have to keep it shaken up or it settles out. Such has ~no effect on vapor pressure and thus flashpoint.
