50/50 penetrating oil

[papabug71]

I dont remember if I got the idea from someone here or over at the A body site I visited when I had the Duster. If you guys are ever looking for a good penetrating oil, like PB blaster or open & shut try this out.

Mix 50% type F tranny fluid with 50% acetone in a big heavy duty squirt bottle. This stuff is like MAGIC ! I never made any of it untill this afternoon. I needed something to help with the original, never removed ubolts on the truck. This stuff will actually attack gunk in threads & kinda foam up. Like peroxide does on a cut, if you will.

I'll never buy PB blaster again

I'll have to mix some up and try it. I was in a parker hydraulics showroom today and they had a big loctite display with a new(er) product that's 1/2 penetrant and 1/2 freeze spray. Supposedly, you spry the stuck part, it freezes to a rediculously cold temp and somehow allows the oil to get in between the parts better as it warms up. Supposed to break anything loose in 1-2 minutes. Anyone try this stuff?

frozen rust? well we will see i guess. give it time for more people to use it. and we'll se if it works or not. most fo the suck rusty stuff i have seen around ehre is so bad nothing gets it broke loose. thats just the way it is with our enviorment.

Never herd of it. Is it made by locktite ?? I'll have to keep an eye out for it.

On a side note, I've been using this 50-50 stuff for the last couple of days on my rear spring project & I must say, it's nasty as hell. It makes a hell of a mess. Works good tho

I read somewhere that a magazine did a test on penetrating oils and the 50-50 mix won. They rusted 5 bolt-nut combos and used a torque wrench to see which took the least energy to break after soaking in pen oil. If I remember correctly 50-50 was best, then Kano Kroil, them Liquid Wrench, then P Blaster, then WD 40.

The difference was substancial too. Kroil took around 125 ft lbs while the 50-50 took like 60 ft lbs. The WD took over 200 ft lbs.

Well, be sure you put it in something strong. I mixed up a bottle of it in a $8 dollar "heavy duty" plastic spray bottle no more than a month ago.

I opened up my cabinet tonight & it had ate thru the bottom of the plastic bottle & leaked all over everything. What a mess

I guess i'll put it in a metal oil can from now on

I use a small glass bottle and an acid/flux brush.

Been putting it on some salt road/rust-belt RUSTY bolts for a week now... we will see how much it helps when I go to pull it all apart.

[papabug71]

Cool beans. I hope it works for you. It helped when I removed my factory U bolts

I remember when BobbyFord made a post about the 50/50 mix and showed the lab results of different peneterents compared to it, I tryed it myself. It dosent like to stay mixed up very well but will knock the bond right out of some rust. i keep some in a old oil squirt can and just give it a good shake before useing it. Ive tryed it on some cruddy rusty stuff and it will get in there and break it lose. If someone could figure out a way to keep it mixed and put it in a can thay would be a multi millionare.

[papabug71]

We could just put a label on there that says "Shake well before use"

I have used that ATF/Acetone mix also. I think it works great. I did notice the separation of the fluids you talked about. So i just give it a shake before i use it.
Cheapest best working rust buster i have found yet.
