What Customers Are Saying

Customers overwhelmingly praise this penetrating oil for exceptional rust-breaking performance, consistently freeing seized bolts and frozen fasteners where competitors fail, with many reporting dramatic results within minutes and calling it their go-to lubricant. However, a significant concern undermines satisfaction: many users report spray cans losing pressure prematurely, leaving product unusable when half full, even on new cans. Some mention strong odor and flimsy spray mechanisms. Despite packaging frustrations, most customers consider the liquid itself highly effective and worth repurchasing.

Great Product, Terrible Spray Cans

Would Not Recommend

PB blaster has always worked great for me until recently. The product is still great but the cans run out of pressure. I use a lot of this product and every time, the can runs out of pressure when there's between a third and half a can of product left. If you can't fix this, can you at least make a non-aerosol can? The 128 oz is too much product to store but a 10 or 15 oz would be great. For the 1st time in 30 years I'm going to have to start using something else.

Locked Spigot

Would Recommend

I broke a spigot on the back of the house. Probably been there since the house was built in 1955. I ran out of my Blaster Penetrating Catalyst so tried everything to get it off, including heat from a torch. Nothing worked. Went to the local hardware store to replenish my Blaster supply. Sprayed it on and broke it loose 10 minutes later. This stuff is awesome.

Cans lose propellant pressure.

Would Not Recommend

I have long used PB Blaster and love the product. However, new cans lose propellant. I have three cans in the shop, all about one-half full with NO PROPELLANT to use product. I am not only victim of this quality issue. This issue is TOTALLY UNACCEPTABLE. PB Blaster must FIX this problem or customers will unwillingly find an other product.

Terrible Quality Cans

2nd can I had that failed. 1st can with standard spray nozzlew just started spraying and would not stop. Ended up all over the car and garage before I could throw it into the yard. It was just a year old. 2nd can I purchased with the new Pro Straw and it doesn't work right straight from the store. You whole cap fell of before I could even use it and no matter where you adjust the nozzle it doesn't spray until you hit a certain spot and then it shoots a huge amount all over the place. Went back...

Love this product!

Would Recommend

I've been using PB Blaster since childhood when my dad would use it, along with me working on thing from lawn mowers to tractors, and our old 81' F150. I grew up in the rust belt in Nebraska, and this stuff just creeps up into the threads and works fantastic. It also doesn't evaporate. I accidentally sprayed some on accident once onto the shelf of a buddy's grill, and it had a few drops on it. We came back out later on that evening and the whole shelf was covered in oil. I was surprised at ...

Prostraw Version

Is there a locking mechanism on the Prostraw Version or did I just purchase a defective can. Won't let me press the spray button

Great product

Would Recommend

I’ve been using Blaster for the last 10 years. I find it useful for two cycle engines. Every year before start up I spray into spark plug hole and carburetor and let it sit overnight. It’s also a good penetrating oil.

Outstanding customer support!

Would Recommend

A great product means nothing without good customer support but PB Blaster excels in both categories! After dropping a can of the garage lubricant while lubricating the garage door wheels and snapping off the stem, they promptly sent out a replacement can. By mistake, they sent out a can of their dry lube lubricant and when alerted to that, they are sending out a can of the garage door lubricant. I've dealt with companies that don't even respond to a concern or complaint. PB Blaster goes the...

prostraw massive pain in the butt.

Would Recommend

I am a certified Chrysler technician. 30 years plus. I go through a can of Blaster a week, or at least I did. I recently when into my parts department and received a can with a prostraw. I gave it a try and it was terrible. I can't get it in any tight spots without the straw closing and it is cumbersome. I asked for a can without it and non of the parts stores in town carried them. I am now using other products. I'm disappointed enough to write a review, and not use 50 + cans a year. Which can l...

Great Product

I have a can of this my Dad purchased about 30 years ago. I used the same can to loosen up some bolts on a trailer and it worked great. I was surprised because of how old the can is and it still sprayed perfectly.

Treashed.....TWICE! Never again.....

Would Not Recommend

Absolutely the best penetrating lube on the market WITH THE WORST NOZZLE ON THE MARKET!! The ProStraw is CRAP!! I thought the first time it was my fault but after throwing away my second (ALMOST FULL CAN!) after it ran out of gas, that was proof enough. If I can't get a regular spray nozzle on it, it will rot on your shelf.

Great product when you can actually get it to spra

Would Not Recommend

I bought a can with the adjustable sprayer and it didn't work. No matter which way I adjusted it, I could jam the button all the way down, but it didn't work. I bought another can and the pressure ran out while the can was still half full. I prefer to buy this, but I'll be switching back to Liquid Wrench until you fix this.

The lug nuts on my 51 Chevy truck were stuck so bad the 1/2 impact didn't make them move at all. I grabbed the pb blaster sprayed them down. I came back a few minutes later and they came off. I couldn't believe it. Now it's my go to for anything rusty.
