WD-40 Specialist Penetrant with Smart Straw, Penetrant for Metal, Rubber and Plastic Threads, Locks and Nuts, Industrial Strength Fast-Acting Formula, 11 Oz.

This WD-40 Specialist Penetrant is a rock-solid 5-star product that belongs in every garage, shop, and toolbox. The fast-acting formula works quickly on rusted bolts, frozen nuts, seized locks, and corroded threads that would otherwise require a breaker bar and a lot of frustration. It penetrates deep into tight threads and hard-to-reach areas, breaking up rust and corrosion without damaging the surrounding metal, rubber, or plastic—which is a big deal when working on delicate or older components. The Smart Straw applicator is excellent for switching between a broad spray and a precise, targeted stream exactly where you need it, with no straw to lose track of. Whether I'm working on the RV, vehicles, or shop equipment, this penetrant has bailed me out on more than a few stubborn fasteners that nothing else would budge. Industrial strength performance in a convenient aerosol can—it does exactly what it promises and does it well every single time. Highly recommended.

Great stuff I had a pain in the A$$ lug nut to remove even used a whole can PB blaster some new stuff they had come out with. Used it over a few days treating it. I put this Stuff on it an hour later it came off. There was another one but had to soak the nut overnight but still came off. Also it works wonders on bionic legs too. Mine got stuck and couldn’t get it off. lol anyway it’s explained in the video. Don’t mind my voice I hate it.

WOW. Could not turn the metal sleeve on an old tub knob to remove it at all-would not budge. spray this in the sleeve and let it sit overnight. Sleeve unscrewed so easily!! Amazing

If you're trying to crack open a rusted bolt on a car or just getting a stuck garden hose off the spigot, this stuff is great because it actually seeps into the threads instead of just sitting on top. The flip-up straw is the best part—you don't lose it like the old red ones, and you can aim it right into a tight spot, like a squeaky door hinge or a seized padlock, without getting oil everywhere. It’s a solid tool to have in the drawer for when things just won't budge.

Worked well to get a stubborn oxygen sensor unstuck.
