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

RE: WD-40 Specialist Penetrant With Smart Straw, Penetrant For Metal, Rubber, And Plastic Threads Excellent product and by applying repeititively for several days, saved a dozen expensive locks for re-use saving lots of money. Also works really well on loosening up manifold bolts to remove boat manifold bolts in order to remove manifold gaskets and then install new gaskets able to save all bolts. Will use to loosen boat control cables to prevent stretching and destroying them as well saving lots of money.

Great spray nozzle delivers product to the right spot

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.

This lubricant works very well for any of those pesky home projects that need a bit of loosening and oiling and is a GREAT price.

Works well for its intended purpose. Very helpful product for automotive work. Helps break tight suspension nuts/bolts loose on 20 year old vehicles. Makes loosening highly torqued fasteners much easier, which helps avoid breaking bolts, or stripping. just spray a little on and let it sit for a couple minutes and it will make work easier. Highly recommend.

Works good and not messy but it does spray a hard stream which is good depending on what your doing. I used it for a seatbelt latch and it fixed it.

Same awesome WD40 that we all love and need - but with a wonderful new spraying option. And the price is so good I thought I was getting a small size. But it’s the big can and it’s a big deal! Must buy! Gotta have it! WD40 at it’s best!!

W-D40 always works well. Thank you.
