WD-40 Specialist Rust Release Penetrant Spray with Blu Torch and SMART STRAW SPRAYS 2 WAYS, 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.

Smart Straw, Smarter Fix I’ve used a lot of penetrating oils over the years, and this WD-40 Specialist Penetrant really stood out as one of the better ones. The “Smart Straw” design makes a surprising difference—you can flip it down for a wide spray or snap it up for a precise stream, which saves both time and waste. I used it on a stubborn garden hose fitting, some squeaky hinges, and even a rusted nut on my lawnmower, and in each case it loosened things up quickly. The formula seems to work fast, cutting through rust and corrosion so you don’t have to force anything and risk breaking parts. Another big plus is its versatility. I felt comfortable using it not just on metal, but also around plastic and rubber parts where I’d normally hesitate with harsher sprays. It dries fairly cleanly and doesn’t leave a sticky residue that attracts dirt, which is often a problem with cheaper sprays. The can size feels generous and should last through many household and garage projects. If I had to nitpick, the smell is strong—like most products in this category—so I recommend using it outdoors or in a ventilated area. But in terms of performance, it does exactly what you want: frees things up without fuss. Bottom line: A reliable, fast-acting penetrant that’s made my life easier on everything from locks to mower parts. The Smart Straw alone makes it worth choosing over generic brands.
