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.

it worked after several sprays and letting it sit 5-10 min
had a stuck hose connection on my washing machine feed into the wall, I was afraid I was going to break the pipe I was prying so hard , so I stopped and got this out, sprayed in once, nothing , let it sit sprayed it again, nothing, sprayed a third time and let it sit and I got it off with some effort, but the product worked, upon observation the thread s were totally shot and rusted , thats why it did not come off. So it does work, not sure about rusty bolts
