Face it: It sucks when nuts and bolts rust and freeze into place. They’re the white whale to our Ahab — difficult to catch hold of and frustrating to an extreme once you do.
Well, a company called J. Walter Inc. claims to have the solution.
Cold Shock is (according to its maker) a fast acting penetrating oil that super-cools bolts to -30°F causing a “cold-cracking” action of the rust and corrosion. This “cold-cracking” process allows the penetrating oils to seep between threads to loosen rust, (hopefully) allowing the nut or bolt freedom from its rusty prison. J. Walter claims to have had success on bolts up to 3″ in diameter.
Anyway, Cold Shock is available for around $13 in 400ml aerosol cans. It sounds pretty slick, though we’re not sure what happens if you get some on your hands. One of the few things we imagine sucks worse than frozen bolts would be “cold-cracked” fingers.
If you’ve tried this stuff, let us know. In the meantime, we’re gonna order some and check it out.

From Reader Comments: Bob says, “Candle wax works great at loosening stuck bolts. For some reason it penetrates great and lubricates the friction surfaces well. You have to get the surfaces really hot, like Oxy Acetylene torch hot, and that creates the hazard of the wax’s vapor lighting on fire. You have to be careful of that.” He attributes this tip to the Oldsmobile Enthusiast community, and says he’s had good luck with it. Click through this post to see the full comment.
