What Customers Are Saying
Customers overwhelmingly praise this penetrating oil for exceptional rust-breaking performance, consistently freeing seized bolts and frozen fasteners where competitors fail, with many reporting dramatic results within minutes and calling it their go-to lubricant. However, a significant concern undermines satisfaction: many users report spray cans losing pressure prematurely, leaving product unusable when half full, even on new cans. Some mention strong odor and flimsy spray mechanisms. Despite packaging frustrations, most customers consider the liquid itself highly effective and worth repurchasing.

[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.

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.
