Penetrating Oils

[MarsChariot]

One day I was reading along here and somebody mentioned using "PB Blaster". And that brand seems to come up all the time. Funny thing is, I had never heard of PB Blaster before. I had always used Liquid Wrench, so I wondered if times had moved forward and left me behind. But then I saw a reference to this article where they measured the effectiveness of different brands on rusty bolts measuring the break-away torque. The lower number is the better oil. Looks like PB blaster is only slightly better than WD-40, Liquid Wrench is twice as good, and ATF-Acetone is twice as good as that. Useful to keep in mind next time you are at the automotive fluids shelf in the parts store.. No wonder most of the the C4s in Broncos leak so much......

And I just bought a new can of PB Blaster today! WD-40 has a new product out as well so I am trying that currently too.

I'm going to start mixing atf and acetone.

I keep saying I am going to do that Pat too, but it always seems easier to buy a can, still break bolts and rip the skin off of your hands! ;D

does anyone know the ratio of ATF:Acetone mix?

K/Y is a good penetrating oil.

 

[brownb4]

haha, ADD kicking in tonite;D

K/Y is a good penetrating oil.

While this may be lubricant, it is NOT an oil, but rather a water based product...

well I'm not going to mix acetone with it.

Ya, but still good for penetration.;D

You can break a nut loose using it.

Glad you did not spell acetone with a few s'! ;D

kroil is light years ahead of the other products sold. atf and acetone must make the bolts fall out!!

Kano is great,but too HIGH$$ and for me and my test subjects I like the PB BLASTER.I quit using W-D 40 along time ago.Diesel fuel is good for Penetrating.I have broke free several stuck single cylinder dirt bike motors with that stuff.I guess it's just what each person prefers and or can get.

Sometimes a little friction is a good thing;D

 

[ilovemaui]

My vote is for PB.
