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.

Always keep a can handy
[This review was collected as part of a promotion.] I use this product all the time. From working on vehicles or equipment, and even around the house for sticky doorknob and latches. Love it and always keep a can or 2 handy.

Works great
[This review was collected as part of a promotion.] Worked better than I expected on some rusted bolts I couldn't budge. I sprayed it on, let it sit for a few minutes, and they came loose with much less effort. The smell is strong, so I recommend using it in a well-ventilated area.

Powerful penetrant with smart nozzle control for precise, efficient application
[This review was collected as part of a promotion.] I recently used the PB B’laster Penetrant, and it’s easily one of the most useful products to have in the garage. It works really well for loosening stubborn nuts, bolts, and rusted parts, but what impressed me most is the design of the nozzle system. I really like the dual-nozzle setup. The longer nozzle gives me finer control and makes it much easier to reach tight or awkward spots without spraying everywhere. Then, when I need more coverage...

Works great
[This review was collected as part of a promotion.] This stuff works very well and fast. As soon as I sprayed it on the rust came right off. Though I don’t have any rusted parts right now I found some rusted screws on my truck to try it with.

Revolutionary penetrating action for old rusty tools!
[This review was collected as part of a promotion.] This product was provided to me from Influenster for my honest feedback. This BLASTER product is amazing for keeping rust off of products and to loosen stiff parts. One spray of the penetrant and my channel locks were moving much more freely than prior to using it. The odor is very strong, so don’t use this indoors. Very easy to use!

Best penetrating oil on the market without a doubt.
[This review was collected as part of a promotion.] I’ve used PB Blaster for as long as I can remember as I grew up in a garage and my father and grandfather owned a body shop and swore by this stuff. It is without a doubt the gold standard when it comes to penetrating fluids. I have lost track of amount of times this has saved my behind when I was in a rough spot, it literally works miracles there really isn’t anything I’ve encountered that even comes close. The potential uses are for this wond...

A little bit goes a long way
[This review was collected as part of a promotion.] A little bit goes a long way as it is an oily liquid consistency! I applied this to a squeaky door hinge and within a few minutes of letting it soak, no more squeaking! It’s also a good option to help loosen stubborn bolts. It does have a strong odor, so it’s best to use in a well ventilated area or keep windows open.

OG + new bottle
[This review was collected as part of a promotion.] This original PB blaster is the best for breaking stuck items loose and ensuring they're still lubricated. I enjoy that the can has a tube nozzle that you can use for precise application plus a slider to control how much is dispensed.

Great motivation for stubborn rusty bolts
[This review was collected as part of a promotion.] PB B’laster Penetrant is great for those stubborn bolts and screws that drive you insane and make you start looking for a larger bar or power tool to remove. It helps provide motivation to those bolts so you can continue on with your project. It helps break up rust and grime on vehicles, lawn tools, and so much more. The product includes a straw that provides the ability to pinpoint the stream for hard to reach places and helps limit the amount...

My preferred penetrating oil for all things rusted.
[This review was collected as part of a promotion.] PB blaster has always been my go to penetrant for all things rusted. Living in the northeast where road salt is life in winter, anytime you have to do anything with a car if you don’t have a can of some sort of penetrating oil on hand, you’re gonna have a heck of a time breaking anything loose. I do like that this can has the spray hose attachment folded and attached to the can as I always have a habit of losing that. It will make for a less me...

Takes care of the job
[This review was collected as part of a promotion.] Aggressive penetration it uses a high capillary action formula that actively creeps into gaps, dissolving rust, surface tension, and corrosion.

Liquid wrench
[This review was collected as part of a promotion.] PB blaster is my go to penetrant spray that I use. I’ve used it for over 15 years and it really helps loosen stuff up. The key is to soak it overnight if you can. It slows goes through the nut and bolt and loosens it. Highly recommend it!
