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.

[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.

Excellent for RV use
I was having trouble opening my RV's black tank valve to empty it. I tried the other spray. Didn't work. Tried this and it worked! My only criticism is the spray doesn't work consistently. It was very hard to get the straw in the right position for the spray to work or to even press the button to get it to spray. Might it be a defective can? Maybe.

PB Blaster exceeded expectations after a few applications, outperforming other penetrating oils.
[This review was collected as part of a promotion.] PB Blaster worked way better than I expected. I used it on a siezed door jam roller, and after letting it soak and spray a couple times it started to move freely. I've used multiple different penetrating sprays and none have ever worked. The spray nozzle makes it easy to apply exactly where needed, and the smell isn't as overpowering as some other penetrating oils I've tried. Definitely recommended for everyone to have a can of this in their ga...
