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.

Blasted stuck plumbing

Would Recommend

I tried to remove the cap off of a 30 year old Delta shower cap. I knew if I applied too much pressure that I would twist the valve and have to replace the whole valve. I Tried applying pressure while tapping, WD 40, everything. Then I tried PB Blaster. I sprayed it and waited for one day. I thought I was going to have to cut it off. But, after using the PB Blaster, it spun off like it was hand tight. Anyone who has taken on plumbing task knows how I feel right now. Job done cheap. Thanks PB Bla...

The most important tool you will ever own.

Would Recommend

Currently restoring a 1951 Ford 8N tractor and so thankful that I have PB B'laster. The time and grief you will save yourself is priceless. If anyone is doing a restoration project, the first tool I would recommend they have is PB B'laster. So grateful my dad taught me well while teaching me mechanics as a kid.

B'laster Got Us To Safety!

Would Recommend

Hello, my wife & I have an interstate hotshot transport business. During some very bad winter storms last month in Utah, my wife noticed a squealing sound from the front of our '97 F350 diesel pickup pulling our 32' freight trailer. We pulled into a rest area thinking a wheel bearing had gone bad & upon opening the hood, we found that our fan belt-tensioner pulley had locked up with our fan belt squealing across it. We were still 30 miles from any civilization in icey, bad weather & had to think...

Insanely great at freeing bolts.

Would Recommend

I am an atheist but I believe in PB Blaster. I have removed so many ridiculously difficult, rusted, old things by spraying on Blaster once every couple of days for a week before spending the weekend under the car. Bolts on exhaust systems used to be hopeless because they're rusted and heated to oblivion by normal operation of the car. Now Blaster makes them turn right out. So many times I have avoided spending huge amounts of money or junking cars because I just barely managed to get a bolt ...

It works but only once

Would Recommend

I have now purchased 3 cans and all three I used one time and left for a few months only to need them again and no pressure. At the price, I will only buy when wd40 doesn’t do the job. I am disappointed that they can’t invest better in the cans and pressurizing, the actual product is bar none amazing on 20 year old Jeep bolts.

PB Blaster works everytime

Would Recommend

Working on a car wash system and had to remove a bunch of rusted bolts and as usual the hex head is no longer that shape anymore so I drenched them in PB Blaster and gripped the vise grips on it and said a prayer........boom they unscrewed like they weren't even tight.

Loses pressure, doesn't spray

Would Not Recommend

This product is amazing, we use it often. Unfortunately we have noticed most of our cans clogging and not spraying after being used one time, they are usually 3/4 of the way full and we can no longer use.

Good product but

I purchased 6 cans part no 16PB and every can ran out of propellant long before product was used. I punctured the cans and recovered 13 ounces of product. All cans were at room temp. SUCKS

Worked Quickly on Stuck Wheel

Would Recommend

I bought some PB Blaster to help get an aluminum wheel off my car when I got a flat. Nothing was moving this thing, not even a 5 pound sledge! Sprayed some PB Blaster, waited a little while, hit the rim a bunch more times and off it came. Thanks for such a great product.

can loses pressure

Would Not Recommend

As other reviews have stated, the can will lose pressure well before the penetrant gets low. This is a waste of product and of the consumer's money. For this product at least, they should change the container to one similar to lighter fluid.

Works but can is terrible

Would Not Recommend

We bought a can a while back and it worked for the job. This morning we woke up to a horiffic stench through our entire house. The bottom of the can failed leaking all over 5 shelves, a bunch of tile to be instaled, and a variety of other construction materials as we are in the middle of amrenovation. This is extremely disappointing, as well as extremely dangerous. I will not be recommending this product because it is a safety concern. We will now have to replace part of the floor as well as th...

Can runs out of pressure.

Would Not Recommend

I like PB Blaster, it's overall performance is very good. The main problem is the cans run out of pressure long before the can is empty of product. I'm a shop owner and order by the case and the last two case all had this issue. You end up wasting about half of the product that can't be shot out of the can.

Does what it says

Would Recommend

Great stuff, but I just had a can that was 3/4 full, blow out while sitting on the shelf. It appeared that the bottom of the can suddenly failed for no reason. The garage now smells heavily of the stuff. Additionally, the wood shelf that it was sitting on, is now completely saturated with PB Blaster. Please contact me regarding a resolution to this matter.
