Industrial Strength Penetrant That Gets Into the Tough Spots Every Time
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.

WD-40 the good stuff
Awesome stuff. I also use their WD-40 special silicone on my RC trucks and the winter or ripping through the rain / mud. Like the Dual end spray with the flip up straw odor is in as bad as PB Blaster. Great for breaking Rusty boats loose just let it sit soak for a good 5 minutes. Good size can happy with the purchase definitely recommend it damned the wrong with WD

Helps with squeaks
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.
