What Customers Are Saying
Customers overwhelmingly praise this penetrating oil as the most effective solution for rusted, seized, or frozen bolts, with many calling results miraculous and noting it works faster and more reliably than competitors. Beyond breaking rust, reviewers appreciate its dual role as a light lubricant that leaves a protective film, preventing future seizing on hinges and mechanical parts. However, a significant frustration persists: spray cans frequently lose propellant pressure when one-third to one-half full, rendering remaining product unusable. Some mention strong odor requiring ventilation. Despite spray can defects, most customers consider this the industry standard for rust removal and keep multiple cans on hand.

Would RecommendUse to think WD-40 was the way to go in the start of my mechanical career, but one day I found an old can of PB in the shop, and never went back! Great stuff

Fails to spray
Would Not RecommendAGAIN I have a almost full can of PB Blaster that fails to spray. I cant tell you how many times this has happened to me with this product.

Give it time to work. At least a half hour.
Would RecommendGood stuff, spray it on and give it some time to work. Sometimes a little heat helps.

Always have a bottle around
Would RecommendYou just can't beat PB blaster, had a wooden window stuck for years, spray PB and left it overnight. The next morning the window popped open and now glides great.

Great product when you can actually get it to spra
Would Not RecommendI 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.

Ineffective
Would Not RecommendTried using this on a rusted sink connection. Followed the instructions, gave it plenty of time to work its way through, even sprayed it a second time, but it did nothing other than stink up the place and make everything greasy.

Time saver
Would RecommendThe 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.

Works Great
Would RecommendThe receiver and the hitch on my 2000 GMC started to rust together. It was to the point that the only way to change it was with a big hammer. I spayed both sides a couple times and let it sit. It ate threw the rust and now it slides in and out with ease. Now once a year I spray inside the hitch and it keeps it free

Didn't think it could do it
Would RecommendI was able to remove a set bolt from a 75+ year old Hand Pump. The steel bolt was in a cast iron housing and there was so much rust it looked like they were welded together. Several hours of soaking with PB and applying heat and ice I was able to free up the bolt with no damage to bolt or housing.

Fixed a seized alternator.
Would RecommendSaved cost of a new or a rebuild kit. Am wondering if it will cause damage down the track, is it an abarasive?

Can runs out of air before fluid
Would RecommendI like the blaster but this last case I purchase has been leaving me with 8 out of the 12 can drained of air with fluid still left in the can. It's bad enough that I just knock a hole in the can body and dump out whats remaining to try and get some use out of them. Air/Fluid ratio not correct? I don't typically hold my cans upside down or anything to cause it.
