Best chemical to spray on rusted bolts?
What have you guys found to be the best thing to spray on rusted bolts to loosen them up?

My personal order of preference for penetrating oils:
1. PB Blaster
2. Liquid Wrench
3. WD-40
And if you can spare the time, definitely hit it, let it sit overnight, then hit it again before your start work. Worth the wait if you're not rushed or on a schedule (got school or work in the morning).

PB Blaster is great stuff, we used to use it in kragen to free rusted water pump studs. Just let it sit on the bolt and work it around in there. Be patient and it will help!

PB blaster is something else (certainly smells like it). I used it when i was removing my old manifolds off my gta and after that stuff did its business you could practically hand-loosen them. Liquid wrench and WD40 work pretty well too...

At my former work site (General aviation maint) we tried everything on exh manifold bolts/studs and wound up using a product called "Mouse Milk".
It works great on rust, but it's expensive ($17 for 8 ozs a few years ago) and really hard to find.
I bought a bottle abt 8 years ago and still have abt 1 oz left..
It goes a looong ways.
I used it recently on my sway bar end links.
They haven't been apart in 20 years, but came right off using the mouse milk.
If anyone is interested,

PB Blaster again! That stuff is awesome.
Of course since I've moved from OH to GA I don't have a problem with rusted anything. My can of PB Blaster is collecting dust on the shelf.

I don't know how much it costs per can, but I use it at work (powerplant) and it works wonders on getting off bolts that have been in 2000*+ heat and years worth of ash build up.
I'm going to look for that Pb Blaster though, seems like a lot of people have been happy with it.

the absolute BEST way to get a rusted, or any stuck bolt out is to hit it with a torch and get it cherry red. Then as soon as its red hit it with your penatrating fluid.
I used to do that to get oil gallery plugs out....after you do that they come out like they were just put in there....

Yup, PB Blaster or Kroil are good choices.
Another good technique is to heat with torch, and then zap them with 'Freeze Spray' which is used for troubleshooting electronics. Get it at Radio Shack. I dont reccomend re-using any bolt you try this on though, as the rapid heatingcooling cycle may sometimes crack the bolts. I split a 3/4" dia. grade 5 set screw doing that once.

Used to use Kroil and that works good. But I've switched to Deep Creep now seems to work a little better. Many times i can remove the nut from the manifold studs with my fingers after breaking loose. Deep Creep is a Seafoam product.Havent tried blaster yet Creep works too good to change.

I bought some PB Blaster and it worked pretty well on 2 of the bolts. I still had to use a torch on a couple bolts and a hacksaw on the sway bar endlinks. This car was pretty rusted underneath.

From experience with my 2 cars, the end links should be destroyed and replaced anyway.

Re: Best chemical to spray on rusted bolts?
I suggest using a pry bar to take some of the stress off the bolt before you vise grip it. and yea vise grip it, as tight as you can get them. SO tight that if they pop off the speed with which they pop off causes enough friction to make the air around them as hot as the sun.
