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.

It gets the job done.
[This review was collected as part of a promotion.] I received this product in return for my honest feedback an I got to say this thing works better than wd40 and since I work in a powdercoating shop is a plus that it's silicone free I strongly recommend this product to anyone.

Works like magic in as little as 30 minutes
[This review was collected as part of a promotion.] This penetrating oil works miracles. Just a bit of it goes a long way. Spray a little on a rusted bolt and watch it eat at the rust. The best part is, in most cases 30 minutes is all that is needed. The included straw easily folds down and stays in place, no longer going missing after the first use.

Excellent product
Would RecommendThis 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.

A must have in your garage
[This review was collected as part of a promotion.] This product broke through the layers of rust quickly. It sprayed out in a pinpoint stream allowing me to get the product exactly where I needed it to. It does have a strong odor, so make sure you are using in a well ventilated area. You can use some degreasers and hot water to clean up any mess you might of made. Just know it will leave a greasy residue because this is supposed to be a long lasting lubricant. I will always recommend PB Blaste...

Solved by problem, but difficult to control spray
Would RecommendI 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.

Lubricate and break free
[This review was collected as part of a promotion.] I’ve been using PB B’laster penetrant at home and at work to break free bolts, nuts contaminated with rust. It’s a must have lubricant that acts quick and easy to use unlike a torch.

Works well!
[This review was collected as part of a promotion.] My back door shifted over the years and needed to remove a screw off of a hinge to readjust it. This spray did the trick! Came out very easily and the product was very easy to apply. Didn’t cause any stains, however, there was a strong chemical odor which I expected. I didn’t need much and let it soak for a few minutes and it worked well. Very happy!

This stuff is a must, saves time, effort, and frus
[This review was collected as part of a promotion.] I used the PB blaster on my trailer to loosen up some old rusted bolts and it worked way better than expected. The spray penetrate deeply into the threads and start breaking down. Rust pretty quickly. I noticed a difference within minutes what I like the most is that it doesn’t just loosen the parts. It also leaves behind a light lubricant that helps protect against future rust, which is perfect for traders exposed to the weather like mine. It’...

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...
