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.

[This review was collected as part of a promotion.] The product is very effective. The coverage is very thick, which is useful to stay on the project. The spray, is sticky, so it stays as needed. The nozzle for the spray folds down for storage, which is good.

Great Product
[This review was collected as part of a promotion.] It shocked me how easily it got rid of rust and other gunk build up. It was simple to just spray and leave for a couple minutes and then wipe it off and it penetrates through the unwanted residue.

You can only get through half a can
[This review was collected as part of a promotion.] For all intents and purposes, the product worked as described. It is good at breaking up rusted components, which is what I needed it for. However, it seems the can loses pressure about halfway through use so you can never get through the entire can. After looking up previous reviews, it seems this is a common issue with this brand that happened more frequently with the addition of the prostraw. I also stress the “be patient” part after spray...

Must have for automotive work!
[This review was collected as part of a promotion.] Very easy application. I have been using this on all my automotive work where any bolts and nuts are involved. I’ve noticed that it penetrates and lubricates the bolts well. After letting it penetrate it makes it much easier to loosen stubborn bolts. Definitely helped when doing my brakes on my vehicle.

Excellent penetrative spray
[This review was collected as part of a promotion.] Best product I’ve used for breaking stuck or rusted up bolts/fasteners loose. It’s easy to clean up after and penetrates deep into stuck hardware.

The best in the industry.
[This review was collected as part of a promotion.] B'laster PB Penetrant has always been a great usable product around my house and garage. Whenever I am fixing a car and find a seized nut or bolt, I run and grab the penetrant in order to break loose the stubbornness of the project. As far as noise it does provide great lubrication for any squeaky product. Overall the best in the industry.
