What Customers Are Saying
Customers overwhelmingly praise this penetrating oil as the best available for loosening seized and rusted bolts, parts, and hardware. Many report outstanding results on automotive components, lawn mowers, and locks—often within minutes or after overnight soaking—and describe it as outperforming alternatives. Reviewers emphasize it works where other products fail and stress they keep multiple cans on hand as a trusted staple. Some note issues with can pressure loss or defective spray nozzles, and a few mention strong odor requiring ventilation. Despite these minor packaging concerns, most customers plan to repurchase and consider it an essential toolbox item.

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.
