ATF/acetone vs. PB Blaster or others

I know a ton of you guys use PB Blaster like it's going out of style, but which do you think actually has better results? I haven't tried the atf/acetone mix yet, but I've read others who swear by it. I kinda like the smell of pbb but I want to try the atf/acetone. Also, doesn't it seem more cost effective to have the mix instead of using an aerosol can which doesn't hold much?

PB Blaster=ok. A 50/50 mix of acetone & ATF=Best Ever! Here's the cold, hard facts from the April/May 2007 edition of Machinist's Workshop. They did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better.

Penetrating oil . Average load .. Price per fluid ounce
None ................. 516 pounds .
WD-40 .............. 238 pounds .. $0.25
PB Blaster ......... 214 pounds .. $0.35
Liquid Wrench ... 127 pounds .. $0.21
Kano Kroil ........ 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10

Kroil is the best on the market...but not cheap. However, the atf/acetone sounds interesting...will give it a try.

So this is saying that Liquid Wrench is better than PB Blaster? I hope so because I've always used Liquid Wrench and have been thinking about getting some PB Blaster because I hear it a lot on here. Guess I'm staying with my old favorite...Liquid Wrench!

I used to be a strictly PB blaster kinda guy. Read that other thread about the ATF/acetone. So I went to harbor freight and bought a refillable aeresol can, and mixed some up. Been spraying it on my bumper and power steering box bolts in preperation for my new bumper. We'll see how well it works out.

I like PB Blaster. I love Deep Creep by seafoam. It is pricy but I have no reservations about ruining anything with it.

Being an Auto Shop Teacher, I spray everyting in the shop with penetrating oil before every summer to prevent rust and Deep Creep has been the best so far.

I am going to try ATF/Acetone for sure, the price is unbeatable.

Anything worth doing is worth doing right.

I wave at other Jeeps and get my feelings hurt if they don't wave back.

I used to be a PB Blaster guy, in fact I have about 6 cans on my shelf. Then I tried BG Products penetrating oil. Beats PB hands down.

Acetones pretty bad for you I hear, I would definately wanna be careful handling and touching that stuff. I know PB blaster can eat through cups so would there be anything wrong with putting the ATF/Acetone mixture in a plastic spritzy bottle?

I don't know about the rest, but PB Blaster came to my rescue recently. I was replacing the driveshaft u-joints on a co-worker's TJ. I tried hammering them, even bent the handle on a bench vice to no avail. I remembered buying a can of PB Blaster, and squirted some around the outside of the caps. 2 minutes and a hammer whack later, the u-joints came out no problem.

The numbers speak for themselves here. I too was once a PB blaster user, I still do on ocassion, but I gave the ATF/acetone mix a try and it is now my choice of penetrating oil.
The only problem with it, is the two seperate pretty quickly. So, you're constantly shaking the bottle, but that's a small inconvenience for the performance of the mixture.

Actually, acetone is really not very bad for you at all. It is fairly non-toxic and is non-carcinogenic, remember it is just nail polish remover. However, definitely don't drink it and I wouldn't stand over a concentrated bottle and breathe the vapors. Also it is a very mild skin irritant but it is so volatile that if you spill some on you it will be gone before you can wipe it off. But I would rinse your skin with some water.
Also it is fine to put it in a "spritzy bottle" and that is what I do. Every organic lab in the country uses acetone in a plastic bottle as a solvent.
