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.

Reliable Penetrant

[This review was collected as part of a promotion.] PB B'laster is a standard and effective product for freeing rusted or seized hardware. It successfully broke loose several extremely corroded fasteners on a recent project, performing reliably as expected. This product is a necessary tool for difficult mechanical work.

Blast with this PB B’laster Penetrant

[This review was collected as part of a promotion.] This PB B’laster Penetrant is a perfect lubricant. Just like its name it blasts into any hard to reach area. Loosened rusted bolts and door hinges making the job easy.

Awesome Blaster!!

[This review was collected as part of a promotion.] Alright, let me hype up the Blaster PB Penetrating Catalyst—this stuff is a total lifesaver! Been using it for a while now, and that spray nozzle is clutch for getting into tight spots. The can feels solid, and that “since 1957” stamp just screams reliability. It blasts through rust like a champ—had a stubborn bolt that came loose after one soak, no joke! The smell’s a bit much, but a quick vent fixes that. Hands down, 5/5—this is my go-to for ...

Best penetrant ever

[This review was collected as part of a promotion.] PB Blaster Penetrating Oil has quickly become one of my go-to tools for tackling stubborn, rusted, or frozen bolts and parts. The spray penetrates deeply and works fast—within a few minutes I could feel the difference loosening up hardware that hadn’t budged in years. Compared to other penetrating oils I’ve tried, this one really seems to cut through rust and corrosion more effectively. I also appreciate that it comes with a precision straw fo...

Great

[This review was collected as part of a promotion.] After other lubricants failed, this one did the trick! Within minutes, I managed to loosen a stubborn bolt that hadn’t budged since the car was made at the factory. This stuff is very versatile. I used it outdoors, no strong odor to worry about. Wish I had discovered this sooner! Can’t beat the price.

If it’s stuck, this’ll unstick it!

[This review was collected as part of a promotion.] This is a staple in my toolbox. I keep a can in each vehicle, and one in the camper. I much prefer this to other penetrants. I won’t name them, but there is one in an orange can that’s very expensive. I tried to use it thinking the cost would make it better and ended up shearing a sensor in an exhaust. I used PB B’laster and the other three came out no issues. Hands down the best penetrating spray on the market.

Great for seized parts!

[This review was collected as part of a promotion.] I’ve used PB B’laster for years when I have seized parts. It is effective and fast acting. This can works great for wide application as well as fine application, and even works upside down.

Can always quits spraying before empty

Would Not Recommend

Let me add to the long list of people complaining about the cans always quits spraying long before empty. I've used this product for years, love the way it works, but sick and tired of at half can it always quit spraying. No this is NOT a one time user problem, it has been going on for years. I give up, done with your product.

PB Blater for all of your auto needs

[This review was collected as part of a promotion.] PB Blaster Is great for anything. It works on bolts & nuts that are rusty and even works on pipes. I use this constantly on all of my automotive needs,the extra long spray nozzle really gets into the tight spots for me. Just shake can and saturate it good, and it will come loose.

Really good

[This review was collected as part of a promotion.] This stuff is truly amazing! I love that it comes with the tube for precise spraying. I sprayed this on some really rusted screws and it made them come right out with no problem after just a little bit of sitting to soak. I will definitely be purchasing this in the future

Blast off!!

[This review was collected as part of a promotion.] PB Blaster is the best way to loosen up rusty bolts, caps, and whatever else was long neglected and bonded over time. The drain cover in my basement was rusted to the pipe. Gave it a healthy spray of PB and 5 minute later it feels like I'm Hercules! This is a workshop staple for sure.

Good

[This review was collected as part of a promotion.] PB B’laster is one of the few penetrants that actually does what it promises. I’ve used it on rusted bolts and frozen parts that WD-40 and other sprays couldn’t touch, and with a little patience it usually breaks things loose. It seeps deep into threads, and once it works its way in, the parts move so much easier. It also leaves a slick film that keeps things lubricated afterward, which is a nice bonus. The downside is the smell it’s pretty str...
