Rated 5 out of 5Â 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.

Rated 4 out of 5Â by RednexToyz 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.

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!!

Rated 5 out of 5Â by uturnagain1 the best overall penetrant ever
I have personally been using 16-PB since1963. It is the best product for it's labeled use that I have ever used, and then some. I have seen engines that are frozen because of corrosion of aluminum pistons in steel bores be freed up enough to be disassembled, a couple were even started. some scoring of course, but started and run. NO lie. It is a catalyst that will start a no start engine as long as it has compression, time and fuel, even if the fuel is old and stale. try it and you will toss out most of your other penetrant/lubricants/fuel stabilizers. try the 16tvf, trans valve fix too. it will de-carbon an engine better than having to tear the engine down.

Rated 5 out of 5Â by Jack9 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!
