tearing down a AC 170 to restore and all the bolts are real rusty. WD 40 is not cutting it. What is your favorite solvent to lossen rusty bolts. Thanks.

I thought I would put my 2 cents worth in as well. I haven't used PB Blaster yet, but KROIL works wonders.

Kroil is fine but one better is Tri-Flo. It is amazing. The Kroil will loosen the rust and you can see it wash away as little particles in the liquid much similar to the PB Blaster or CRC-556. But the Tri-Flo actually disolves the rust into a brown liquid. It can actually turn rust into a lubricant. I have taken a totally frozen choke cable and sprayed Tri-Flo along it, let it set 10 minutes, and it worked like new. The stuff is also a great lubricant for things like hinges or bushings. But be warned, it is expensive.

I use them all, but found "Knock 'R Loose" to work best for me. Also found brake fluid works pretty good to.
Just tryed a trick I heard here a while back today. Heat with a torch and then spray with a fire extingusher. Worked good.

PB Blaster gets my vote. Nothing like it. An impact wrench set at low power and used both backwards and forward will loosen bolts you will snap with a 5' breaker bar!

I don't know why I see so many negative things said about WD-40. I have a 1952 CA I completely restored that was a rusted wreck, and I used WD-40 on all the rusted bolts, and was able to remove them without breaking a single one, including the manifold bolts. What I did was lightly wire brush all the bolts, and then daily I would spray a little WD-40 on them all. I waited about three months before I attempted to remove the bolts. I broke not a one, they all came out.

I was impressed.

My neighbor claimed he cured his arthritis with WD40, but then he died a few years back. When I had a bolt that WD40 and heat would not break loose I tried the PB Blaster and it worked. I've never tried Kroil of some of those others, but next to PB Blaster you'll want to save the WD40 for your arthritis...

I have nothing negative to say about WD-40 and have several cans of the stuff. I use it for lubricating parts that need some penetration to go along with the lubrication.

You gave the reason for preference toward PB and Kroil in your post. You waited 3 months to let the WD-40 soak in and work. Had you used PB Blaster or Kroil, you could have done the work in a day or two with even the most stuck bolts.

WD works, but it takes a lot longer.

WELL SAID MY FRIEND! Another product, but a little more pricey is called FREE ALL. Maybe a little better, but perhaps not worth the extra cost. Dave NE Iowa

Hands down.... PB Blaster is first choice.

For the ones that bust anyway, Kroil is the penetratingest stuff ever.

I have about 4 cans of PB around the shop and one can of Kroil. I use them all. Be sure to let the rusted up bolts soak a while before busting them loose. PB has a catylist that eats the rust but it takes a little time.

Back in the late 50s my Dad and I restored a WD that had been thru a barn fire and left outside for a few years. We didn't have a gas torch but we had a "carbon arc" torch which works pretty good on frozen nuts; just set carbons one on each side of a nut and pretty soon it's red hot. I'll never forget the "sweet" smell of "Liquid-Wrench", though!! Nowadays, I like Kroil but it seems that PB Blaster works as well and is cheaper.
