About a year ago I read in farm paper about a way to make your own penetrating oil that is far better than any on the market, so I tried it and if you rebuild any of this old rusty machinery you might want to try it. Mix equal parts of automatic transmission oil and acetone. You can get the acetone any place that sells paint products. I have use it on nuts and bolts that I am sure have not been touched in 50 years or more and ate up with rust. Some of the real bad ones I just set the spray bottle close by and give it a shot a couple times a day for a couple of days and you can almost loosen the nut with a pair of pliers. Maybe this will make somebody's life a little eaiser, it sure has been a big help to me.

ty was told about it years ago but had forgot what to mix the ATF.

Yes,it sure does work. I use the same mixture in dismantling 100 year old firearms whenreplacing stocks and farm machinery here.
As always use in well ventilated areas.

Am getting an old grain drill ready for oats. Been sitting for years. I bought it out of a swamp at a neighbor's who 'inherited' it when they bought their place.

Only one cup left that's still stuck. Been soaking, tapping off and on for couple weeks. Am going to try this formula if the last stuck one isn't free tomorrow when I work on it again.

Thanks for the tip, T. Nichols. An old mechanic friend always used ATF. Never knew about the acetone part.

Looks up "Ed's Red" for another similar formula. ATF is good stuff.

I will have to give this a try. PB Blaster and heat is as standby around here. Learned about it at the fertilizer plant where everything to heat and a little PB Blaster.

I also use PB Blaster. Then tap on the end of the side of the nut. The vibration draws it into the threads. It stops me from having to use heat.
