Rated 5.0 out of 5.0Â by Greg Mechanics Secret
A master mechanic friend of mine introduced me to PB Blaster years ago and said it was truly a mechanics secret. This stuff is the best penetrating oil Iâve ever found! Iâve been able to break seized nuts on exhaust systems that are over 30 years old loose with this before. The trick is to soak the part really well in PB Blaster first, let it soak in for a minute or two, then bang on it with a hammer a few times and let it sit for a bit. Rinse and repeat if necessary, but that stubborn nut will come loose eventually! I always have a can of this stuff around. It smells terrible, but it works great!!

Used it to break free some rusted bolts. Tough jobs may require several shots and a bit of time to perform its job. Requires a little patience.

Rated 5.0 out of 5.0Â by Contractor Works like Magic...but give it time to work
Worked like magic to free a frozen, rusted, galvanized, threaded 1 1/2" pipe from a tee in 24 hours. I'd leaned on this with an 18" wrench and a breaker bar and no luck (and I'm a big guy). Before giving up and tearing out the wall gave PB blaster a try - best $5 I've ever spent.
Scraped away hardened pipe joint compound, heated it with a torch, gave it several whacks all around with a hammer, and then sprayed several shots of PB into the threads and let it sit overnight. Next day it came apart easily.
Really does work but it needs time to penetrate. Don't think you can spray a frozen joint and 10 minutes later pull it apart. Let it sit overnight and it will work wonders.

Had a rusted out bleeder valve that I tried torching, and other penetrates but nothing worked. A friend told me about this. Sprayed it had a beer, sprayed it had another beer, and it came off first try. Best stuff for 5 bucks!!

The hood latch on my car was corroded and it got stuck in the open position. WD-40 didn't help at all, so I tried this. After a quick spray and 30 seconds of letting it penetrate, the latch was freed up and working perfectly.
