WD-40 Specialist Penetrant with Smart Straw, Penetrant for Metal, Rubber and Plastic Threads, Locks and Nuts, Industrial Strength Fast-Acting Formula, 11 Oz.

I have a leaky bathroom faucet. It's an old faucet. I figured I'd take a shot and change the washer. Unfortunately, I found that the under-sink shut off valves were totally frozen. I checked YouTube, and one guy said to spray some WD-40 on the valves and let it soak in overnight. I thought I had some in the garage, but I must've used it up. There was no WD-40 to be found. I bought this one and sprayed it on the valves. I wasn't really expecting much, because the cold valve in particular was totally stuck. I couldn't even budge it with a wrench. The next day I gave the valve a turn with the wrench, and it was totally free. I didn't even need the wrench. I could've easily turned the valve with my hand. This WD-40 came through with flying colors. Of course it worked, it's WD-40. If I could give it six stars I would. absolutely recommended.

Arrived on time and the cost was more than fair! How did it work? What I would expect WD-40 to do. Terrific product as always. And that straw makes it very convenient. Terrific as always!

Worked wonders on our sliding glass door track! No more pulling a muscle trying to open/ shut the sliders. Great little straw house for exact application. Also great on squeaky door hinges!

Unfreezed my screen door. Rolls great. Going to use it on other items. I really like it.

The product itself is established, dependable, and is always a great go to for those little jobs that need lubricating, loosening, or whatever. So five stars for the product.The new spray can, on the other hand, is a huge PITA. If you don't hit the sweet spot just right, you may not get any product at all. When it does work, it works well but you can't always hit it just right. In other words, the spray mechanism is more difficult than it needs to be. I did not mind the days when I had to poke the straw in myself because then it always worked. So about 3.5 stars for the nozzle itself.

Works well no issue with shipping . Strong smell but that’s with the product

WD-40 Specialist Penetrant did exactly what it’s supposed to do — it penetrated stuck bolts like a champ and lubricated as it went. Broke loose some stubborn parts with ease. Definitely keeping a can of this in the toolbox at all times.

A nut would not come off no matter how I tried to the point of accidentally stripping it. A spray of this and it came off like someone already loosened it for me.
