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.

The gold standard for stuck bolts

One of the best products out there
[This review was collected as part of a promotion.] Perfect lubricant to help with those stuck fasteners! The new applicator nozzle is incredible, no more over spray, no more wasted product. I love the ability to gently apply to the areas I need rather than just soak everything for no reason.

Love this product just bought my second can...
[This review was collected as part of a promotion.] I’ve used Blaster PB Penetrating Catalyst on everything from seized bolts on my car to rusted outdoor hardware, and it’s become one of those products I always keep within reach. What stands out immediately is how quickly it works—after a short soak, even heavily corroded parts start to loosen without excessive force. It creeps into tight spaces better than most penetrants I’ve tried, which makes a noticeable difference on older, stubborn jobs. ...

Breaks down and penetrates aged rust
[This review was collected as part of a promotion.] The PB B’laster Penetrant works great on lug nuts. I work on cars and one of the hardest parts is getting lug nuts off and I have to say it works better than anything else. Very durable to work on lug nuts and hard to remove screws. Formulated to help break down aged rust and it will last forever with the proper storage after every use.
