WD-40® Specialist® Rust Release Penetrant Spray

A fast-acting penetrant that gets deep into crevices, threads and seams to break the bonds that hold stuck parts together.

WD-40® Specialist® Rust Release Penetrant Spray is a fast-acting penetrant that quickly goes to work on rusted nuts, bolts, threads, locks and chains, and also leaves behind a protective layer to help prevent rust and corrosion from re-forming. Containing Blu Torch® Technology, a proprietary blend of synthetic additives, it is safe to use on plastics, rubber and metal.

  • Extra-penetrating Blu Torch technology
  • Ideal for use on nuts, bolts, threads and locks
  • 50-state VOC compliant

Great stuff

So I bought a 5l drum and got a tester free. Stuff seems to work good on some rusty threads but works better on really rusty threads with a little heat not much but a little. Unlike normal wd40 this stuff sticks around to once the metal has cooled. All in all I'd buy it (just wish the tester had a bit more than two nuts worth of spray in to test further.)

Another amazing product from WD!

I had a tie rod end jam nut that would not budge with all my weight! 220 lbs! I searched every blog on the web and tried almost everything others had suggested and still nothing! Bought this product today sprayed on when i got home, ate dinner then went at it, and presto!!

Awesome, works better then i expected

Picked this up to try it out on a project i had going. I needed to remove the motor from a pump on a pressure washer made in 1989. I was worried that the shaft was rusted to the pump, or the 4 bolts would be hard to break loose. I sprayed WD-40 rust release on it that night and let it soak for 24 hours. When i went to remove the engine from the pump, it was surprisingly easy. The bolts came off, and shaft slides out no problem.

Doesn't work

I sprayed several times from all angles and over an hour and it never loosened the screw up enough for my power screwdriver in reverse to remove it. Waste of $7.00!

Dependable

Moved about one year ago. Kept the WD-40 close at hand. Sure enough, needed it for the garage door and a rusted padlock.
