Rated 5.0 out of 5.0 by Amazing! This stuff is amazing. First of all, I am not a dude. I am a woman and a little one at that. I am not strong, I do not lift weights. I had to remove two 60+ year old leaking galvanized steel pipes from the hot water supply and return. I used this and the biggest wrench I could find (it goes up to my thigh). It took some patience. I let it sit overnight, banged on the pipe, tried loosening it and then sprayed it again letting it sit for several more hours. I was able to unscrew this on my own with no help. I won’t lie it took effort and several spray and sit sessions, but at the end of the day I have band new pex piping feeding my hot water heater. Thanks PB!! Oh and it also helped opened the old single pane windows. Great stuff! May 20, 2015
Rated 5.0 out of 5.0 by Fantastic. Worked in minutes!! With this oil we were able to remove a semi stripped nut from an awkward area behind our dryer. Also we were able to remove several nuts and adjust seats that were super rusted on some bikes our neighbors gave us. April 10, 2015
Rated 5.0 out of 5.0 by 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 I’ve ever found! I’ve 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!! January 9, 2015
Rated 4.0 out of 5.0 by Break free rusted bolts 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. October 9, 2012
Rated 5.0 out of 5.0 by 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. June 19, 2014
Rated 5.0 out of 5.0 by Best rust penetrant out there This is the best rust penetrant i have ever used. Anything you have that is rusted or corroded that you can't break free, spray a little of this on and let it sit for a few minutes. You will be amazed! May 18, 2011
Rated 5.0 out of 5.0 by Amazing Stuff! 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!! August 17, 2014
Rated 5.0 out of 5.0 by Great stuff!! PB Blaster works great, better than WD-40. PB actually penetrates. April 8, 2015
