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

I believe that this works as well as PB Blaster without the nasty smell. I've had great luck with it and i will buy it again. Read the label...Shake the can. Good price, great product!! Thank you, Seller.

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.

Good stuff. Works amazing. Stops all squeaky doors

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

good product to keep in hand

This WD-40 Specialist Penetrant works very well on rusted bolts and stuck metal parts. The Smart Straw makes it easy to apply precisely without wasting product. It penetrates quickly, helps loosen seized parts, and is a dependable product to keep in any toolbox.

I used it to clean up stationary wood shop tools. Worked great, took rust off cast iron. Has a clean smell, not offensive. Lasts a long time. You can leave it on surfaces overnight.

Effective in preventing rust and squeaky doors. A+
