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...

Excellent product 👌🏽👌🏽

[This review was collected as part of a promotion.] The Blaster penetrating catalyst spray is very effective for repair work, as it helps loosen rusted or stuck bolts and metal parts, making disassembly easier. It has a strong, recognizable chemical odor, so it should be used in well-ventilated areas. For frequency, it can be applied whenever parts are seized, sometimes requiring more than one application for heavily rusted components. In terms of safety, gloves and eye protection are recommende...

The industry standard for a reason

[This review was collected as part of a promotion.] PB Blaster is the industry standard in penetrating lubricants. It is the only cam to reach for when going after a rusty net or bolt. The precision tip and flow adjuster work better than any others in the industry and the can is durable enough to survive the fall off your work bench.

Great stuff to always have on hand

[This review was collected as part of a promotion.] PB blaster has always been my go to for a variety of tasks around the farm. There is no better product for loosing stubborn bolts on old equipment. Spray the blaster on the bolt and wait some time and then loosen it up, I have even waited overnight on stubborn bolts and have had great results. This bottle has an attached straw for pinpoint applications and it works well. If you have never used this product before, it will have a strong odor so ...

PB B’laster is the best!!

[This review was collected as part of a promotion.] I’ve used PB b’laster for years. It’s awesome for stuck bolts and pipes. It will wick its way into the threads. Just make sure to let it sit for a bit before torquing down on that nut! The new nozzles are on slick! The variable settings and spray vs straw really help too. It’s nice to. It have to keep up with the tiny straws like back in the day. It even works as a light lubricant in a pinch!

Great new spray design and awesome product

[This review was collected as part of a promotion.] I have been a PB blaster user for years, this new can design with the slide for more or less spray volume is great. When I want to spray or really just dribble on a frozen set of pliers I usually get it everywhere, but set the slide all the way to the “-“ and you can control it down to a dribble. In addition to the penetrating lube, I like the garage door lube. This new design also is built in storage for the spray nozzle that folds down aga...

Great for breaking down rusty bolts

[This review was collected as part of a promotion.] Doesn’t smell too bad. Breaks down all types of rust and loosens bolts. Usable anywhere. Sprays where you point the nozzle so it won’t get in your eyes. Not too heavy for long spraying sessions.

Must have in your toolbox!

[This review was collected as part of a promotion.] This is an excellent product. I used it to loosen some rusty bolts on my son's bike, and it worked its magic very quickly! Highly recommend having this product at home to help with rusty nuts and bolts. However, make sure to use it outdoors because it has a very strong smell.

Great Penetrant + Lubricant!

[This review was collected as part of a promotion.] So far so good! Was planning to use it and review with while I worked on my car, but had some stuff set back planned projects. My security door hinges are showing signs of rust and make noise when opening/closing. Sprayed some on, and man this stuff is viscous! Which is great! Immediate stop to the squeaking, and it’s stayed that way. Pretty universal in terms of use, instructions are clear, and I love that it has an adjustment tab to contr...

Best product on the market

[This review was collected as part of a promotion.] I’m an average homeowner and use PB Blaster at least once or twice a week. Just this week alone I used to remove stuck lug nuts on my trailer, lubricate the threads on my jack, and on my drill to make it spin like it should. I love that it has a straw attached since I’m always losing those red ones. Not to mention, you can adjust the flow. There’s really nothing I don’t like about it although I use it sparingly inside because my wife isn’...

Works great!

[This review was collected as part of a promotion.] Needed to work on my Jeep and the sway bar was stuck. I used PB B’laster to loosen the bolts. I like the long straw it makes it more safe. The smell is always the same.. industrial.

Great product

[This review was collected as part of a promotion.] I always keep a bottle of this stuff in my shop, and all my work trucks. And I suggest if your working on old stuff or even new you should keep some on deck. I normally go spray this stuff on what ever I’m gonna be working on in the next little bit and let it soak in, and man this stuff will help you out on those stubborn bolts it just helps break up that rust that almost turns into a weld over time. So the performance is there when you let it ...

My garden hose was stuck on the outdoor spigot. Couldn’t get it to budge last fall, cut the hose. Didn’t want to move this spring, tried several things. A few liberal applications of this, 2 hand tools, and a very determined best friend- success!
