Rated 2 out of 5 by from good product BUT can just dont work properly . Buy at least 2 cans per month and in the past thought I could not do without it BUT the last 2 cans I had to throw away at least a third of each can because the cans would not work . no pressure Im thinking ....

Rated 5 out of 5 by from Does what it says 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.

Rated 5 out of 5 by from WORKS BETTER THAN ANYTHING ELSE! I have used and recommended PB for years now after working on my Jeeps. In the rust-belt, I've been able to remove hub bolts, spring eye bolts, exhaust hanger bolts etc using PB. Spray it on, wait, spray again and then put the tools to it. Also works great by soaking rusty bolts and nuts in the liquid.

Rated 5 out of 5 by from The perfect gift for a housewarming :) I used this years ago and was so impressed. I have found a gazillion uses since and make sure to always have a can on hand and frequently give one as a gift! Trust me you will be surprised at the amount of thank-you that keep coming! Have used on roodtop whilybird turbine to unfreeze a rusted stuck one and even squirted a neighbors from the fence line to stop the squeaking that was keeping me up at night. Amazing product! I did have a question if anyone knows, when loosening lug nuts I wondered will it hurt tires? and if not is it good for them or should we be careful to wipe off overspray.

Rated 5 out of 5 by from Stubborn locks no match for PB Blaster! In order to repair the coin op laundry equipment I fix for a living, you have to unlock alot of service panels. Stubborn locks used to slow my workday down. Not anymore. One blast of PB Blaster=no more stuck locks.Thanks for making my job easier PB Blaster.

Rated 5 out of 5 by from Did the job, saved me big bucks I had to remove a quarter turn cartridge from a bathroom faucet. The cartridge was frozen, and I would have damaged the faucet if I had forced it. I tried PB B'laster. Sprayed it on, even gave it a couple of light taps (probably didn't do anything but it made me feel better). Waited about 10 minutes. And there it was, the cartridge came out with hardly any force needed at all. No new faucet, no damage, no cursing, it works.
