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.

Excellent product

This really works great. We had a stubborn valve and it freed it up. The product has a petroleum smell at first, then fades in a couple days.

Solved by problem, but difficult to control spray

Would Recommend

I had a bolt stuck in a 15 year old chair. After about 10 minutes this helped me unstick the bolts. I did find it difficult to spray and although adjustable I always got a bit too much sprayed out. However, it worked well.

Durable, dependable, gets the job done and a great

[This review was collected as part of a promotion.] The selector on the straw spray feature is a great idea and works very well. Overall the entire cap is very durable and stays on even with force applied or drops unlike other brands I've used. I've been using PB Blaster for years and it is my go to penetrant for stuck bolts, nuts, bearings, pins and all sorts of other components that can seize. It leaves a film after drying to prevent seizing in the future which is a great idea as well. It is t...

Highly effective penetrant that makes quick work o

[This review was collected as part of a promotion.] PB Blaster is an essential for any DIY automotive project. I used it to tackle some heavily rusted components in the engine bay, and it broke them loose much faster than other penetrants I've tried. The effectiveness and performance are outstanding. It really saves you from a lot of frustration and potentially snapped bolts. The texture is very thin, which is exactly what you want for it to seep deep into tight threads. The odor isn’t bad and i...
