What Customers Are Saying

Customers overwhelmingly praise this penetrating oil for its exceptional ability to dissolve rust and free seized bolts, nuts, and corroded parts where competitors like WD-40 fail. Reviewers consistently report it works within minutes on severely aged rust, calling it their go-to solution and best on the market. Many highlight its reliability and superior performance compared to alternatives. However, a significant drawback emerges: customers frequently report cans lose propellant pressure prematurely, leaving product unusable despite half the can remaining. ProStraw nozzles also receive criticism for poor quality. A few mention the strong odor as a minor downside. Despite packaging frustrations, most consider the product's penetrating power worth the inconvenience.

Very fast acting lubricant!

[This review was collected as part of a promotion.] This product helped me so much on some stuck nuts I had on my lawnmower. It quickly broke down the rust and I had the nut off quickly! I would highly recommend this product as it worked so easily

PB is the most reliable penetrant out there, now m

[This review was collected as part of a promotion.] PB blaster has been a staple on my toolbox for years because nothing else really loosens rusted on bolts the way this stuff does. You can actually see it wicking into the threads. The latest design includes an adjustment which limits how much product comes out of the straw. Making it customizable to the job. Being able to dial back the flow means I'm not wasting product or making a huge mess. Which makes clean up a whole lot easier. It still ha...

Lifesaver if you are in a bind

[This review was collected as part of a promotion.] This is a top tier product. This penetrating oil can be used to break just about anything open. It is expensive but when you need it, this can is priceless. It will get you out of a lot of tough situations. The straw is also high quality and makes it very easy to spray and not like a random can you find at the auto parts store.

Effective rust remover

[This review was collected as part of a promotion.] Engine work, mudflap or heavy duty shock absorber change PB will do the job. That's the number 1 choice for me ever. PB B'laster Penetrant is safe to use. The drying time is quite quick. I like that the consistency is thin, and it penetrates easily into hard spaces removing the rust.

Give me a break, PB B’lasted penetrate :)

[This review was collected as part of a promotion.] The PB B’laster Penetrant certainly penetrated stubborn rusted screws for safe removal. The can is designed in a bright red and easy to spot in dim environments and is super easy to use. The flip up precision applicator is perfect for tight to reach spots and if I need more, I can just flip it down and go to town :). Doesn’t leave a messy residue and is easily cleaned with soap and water.

Rust genie in a bottle

[This review was collected as part of a promotion.] I have been able to use this penetrant for a few stubborn bolts and it really gets the job done. The spray is easy to control and the built in straw makes it simple to dial it in and hit tight spots without making a mess. It feels solid in hand and doesn’t leak or drip like other cheaper sprays. After letting it sit for a bit, I could actually feel parts loosen up way easier than before. Compared to something like the Wd 40, this feels much str...

The best penetrating oil for breaking loose stubbo

[This review was collected as part of a promotion.] Living in NY, rust is a nightmare for my Camry. I used PB B’laster on my rusted hood latch and the performance was instant. You could see it “wick” into the metal to break up oxidation. It’s incredibly easy to use and essential for older cars!

Save your wrenches and your knuckles. Use PB B'las

[This review was collected as part of a promotion.] PB Blaster is a staple in the shop! There's nothing worse than spending hours trying to remove a seized bolt just to end up stripping the bolt or your socket! Spray on a decent amount of PB Bpaster and go relax for 30-45 minutes. When you return, that stubborn bolt doesn't stand a chance, and you can save your tools from unnecessary damage (and your knuckles!). I used to work on a lot of older classic cars that tended to be rusty underneath, an...

Perfect

[This review was collected as part of a promotion.] I recently tried the Blaster PB Penetrating Catalyst, and honestly, it did exactly what I needed it to do. I had a couple of stubborn, rusted screws that wouldn't budge no matter how much force I used. After spraying this and letting it sit for a few minutes, I was finally able to loosen them without stripping anything.
