Does 'PB Blaster' and other penetrants REALLY work or....?
...is it just psychological?
You often read how people "spray with PB for several days" before undertaking a knuckle-busting repair. My question is if anyone can state with no doubt that there was a significant difference if they had not used PB?
I have noticed a big difference using a MAPP gas torch but I am not really too sure if PB or any other penetrants actually made a difference...except making me more determined.
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.
I too have seen that online. Somebody else posted it on a Mustang forum.
Just watch.... don't want to be putting acetone on any torx bolts outside the body. Underneath, OK.
PB works. I tried to loosen the nut where the track bar connects to the frame side. No luck. So I drove back to school, and everyday before class as the motor was warming up, I'd give it a healthy dose of PB blaster. My next attempt a few days later to remove the nut..... success!
94 YJ w/ stuff. All the work/money I put into it, and the comment I get most is my $20 mod: "Hand throttle?!? That's awesome."

Yes it works well, especially if you can spray on top of the bolt so it can gravity feed down. The acetone is the penetrant. Its not the best penetrant but its the safest. For really stubborn crap you can use a better solvent. Just be careful and read the directions of any other solvents you try
Your limited slip differential sucks.
I'll tell you what really works a four foot pole. But seriously thats pretty sweet I've always wondered the same thing. It certainly seems like PB helps but I never now if thats because I have already started to work the bolt loose before I try PB.
on my winch where the switch that lets the winchline IN or OUT was stuck in the IN postition. i tried using WD40 and it wouldnt budge. went out and bought some PB blaster, well the switch was wrorking the same day, and is still working 1 week later
PB blaster works great! I live by it when doing wrenching on old bolts.

Toss all your cans of PB Blaster away....It's "ok" for rust ....But,
Purchase CRC "FREEZE OFF" that $#@! ROCKS!!!
It's gets deep into the grooves and will let free pretty much anything thats rusted.
CRC Freeze-Off Super Penetrant loosens rusted and corroded nuts, bolts, couplings, fittings, hinges, locks & frozen components. Freeze-Off is a unique formula that immediately drops the temperature of the area in direct contact with the spray. The freezing effect cracks rusted surfaces, allowing Freeze-Off to reach deeper & work more effectively than other penetrants. Lubricating film prevents corrosion and displaces water. This is a low VOC formula.
I will assure you that you will be tossing out your PB Blasters goodbye forever!
You'll be using the "FREEZE OFF" like it's a Rust away god.
This stuff is Awesome!
