PB Blaster or WD40?

While I'm waiting for a screw to unfreeze after liberally applying WD40, I was wondering if anyone had any thoughts on the best screw/bolt unfreezer due to rust. PB Blaster? WD40? Are there any others out there that work? I don't know if anyone has ever asked this question before - at least I haven't seen it.

Re: PB Blaster or WD40?

PB Blaster...it is a penetrating oil that works well on rusty old bolts, etc. WD-40 is a "water dispersant" (WD) product and not a penetrating oil. It absorbs water very well but will not pentrate rust like PB.

This is my choice, The quality of this products is amazing. But if you only have two choices use the PB.

Re: PB Blaster or WD40?

Kroil is well known in the firearm industry and is great stuff. But between your choices PB it is.

I hate WD

Re: PB Blaster or WD40?

We use PB Blaster in our shop, and it works great, but It's no miracle. Still, great stuff though. In the VDOT shop I use to work in the guys there swore on this stuff called "FREE". Supposedly better then PB Blaster, but it cost a few dollars more.


I've almost always been able to remove some old rusty stuff with some PB Blaster and a good torch. Only on a few occasions did that combo not work.

Re: PB Blaster or WD40?

my uncle is a gunsmith by trade. He specializes on weapons made before WWi, and has stuff from the 1400's.
I tossed him a can of PB Blaster a mounth ago after seeing him spraying WD-goat p!ss, and he was amazed. He said it is right up there with the Kroil that he only uses when he has to.

Re: PB Blaster or WD40?

Two different animals.PB Blaster is great for freeing up frozen bolts,not so great as a lube.WD40 is for lube.Lube is good on stuck bolts and will always be a help.even if not enough help.
I use PB Blaster to free things up,then I lube it with WD40 or CRC.

Yepper - but WD is a poor lube IMO. (Can of worms opened).

TRI-FLOW for the win!!!
It is excellent stuff. Pick some up next time you are at the industrial supply store (usually the only places that have it locally). It's what I use to clean my guns, and also to wipe them down - stock and all. Works great. (Edit: Yes, I do still use bore solvent).

Re: PB Blaster or WD40?

The products that get my vote........

PB Blaster for a penetrant.

Triflow for a pivot, cable, chain lube. Hey Orange, many bicycle shops carry Triflow as a lube for bike chains. Also comes in drip or spray.

Yea - I have seen it there too. Just didn't really think of it. I have never bought it there - I always have plenty.

I use it on my bike chain too, though.

I can't find the thread right now but a while back someone mentioned a product that was sold by the Chevy dealers that he said was better than any of the ones mentioned. It was considerably more expensive though.
