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 Great stuff!! PB Blaster works great, better than WD-40. PB actually penetrates. April 8, 2015
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 When I run out of kroil I know this is a good alternative penetrating oil When you have a situation where it's difficult if not impossible to break loose nuts, bolts, and literally everything part around a car this is the best alternative to what I normally use (kroil). I normally have a few cans of my preferred penetrating oil and when I run short I know I can always get PB Blaster aerosol cans at my local Home Depot. The stuff works however you must have patience along with a good wire brush to clean around the area (this removes the old pipe joint compounds, flaked rust, and years of dirt which limit the ability of this penetrating oil to seep into the frozen threads). I just wire brush then spritz it on the fitting I want to break loose then "wait". Depending on your urgency or patience tolerance the more time you allow this oil to seep the easier task will be. $5 per can makes this quite expensive which is why I normally mail order for quantities of my preferred penetrating oil. When you run short, paying $5 per can of this at Home Depot is your best alternative. March 15, 2015
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
