Free All Penetrating Oil, 11 oz.

I had frozen outside hose adaptor that hadn't been touched in decades but I needed to replace it as the housing had a hole and was starting to leak. I tried for awhile to use one plumber's wrench to brace the threaded side so I could use my huge adjustable wrench to take off the housing adaptor. Needed two people and after alot of effort nothing budged. So I thought I'd try this as the only other option was a plumber and sprayed it on it two times (separated by a day each time). The next day I tried it again and to my surprise it started to move!! Took it off completely and saved at least $150. This was a tough test and it worked. Not sure it will work for others as your situation might be worse but I'm glad I tried. it.

Long time, reliable agent. Works great!

Great purchase. I used it on an old 2006 Pontiac g6 to free up the reclining of front seats as they where rusted preventing the full reclining ability of the seat. Sprayed the joint freeing up the rust and they now work with no issues. This is a product I find will come in handy for many projects if the future.

This stuff works amazingly well. Smells bad. The nozzle quit after a few uses. Other than that, a fine product.

Best stuff on the market they don’t sell a side of WD-40 or other type because once you use this, you won’t use those! Absolutely have never got something not to break free after using this product!!! worth every cent✅🛠️✅

Have a Jeep Liberty over 20 years old that threw a code for Throttle Position Sensor. Applied wd40 and waited then tried to turn. It was so tight it twisted a torx bit. Got this and applied at night. Next morning fitted new bit and tapped on end for vibration. I applied bit and turned it out without great force. I've been a mechanic and Body man for 60 years and never had a similar experience. This stuff works. Never posted a review this good before.

I had a transmission drain plug that seemed incredibly tight where I couldn’t take it off with my 3/8 inch ratchet so I sprayed some free all on it and ordered a 24 inch long 1/2 inch breaker bar, which came the next day. I tried to use the breaker bar, but it was too long so I was thinking I would have to jack my truck up to use it but then I tried my little 3/8 inch ratchet again just in case and as soon as I put the ratchet in the drain plug it spun because the drain plug was that loose!

This stuff is the best penetrate I have ever used. I have been a mechanic most of my life and have tried lots of different products, but this one is by far the best.
