Free All Rust Eater Deep Penetrating Oil, 11 oz Aerosol – Loosens Rusted Bolts, Nuts, Pipe Connections & Locks – Industrial-Grade Rust Remover, Silicone-Free, Safe on Paint & Plastic Surfaces, 2-Pack

This is a very good product which performs as good if not better than the more expensive WD-40. I believe the product predates WD-40. It has made my life easier in the garage.

I have had this before, and it worked great. It was a good Value. I still have the first can I purchased, good Quality it still works.

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.

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

This stuff here really works very well

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✅🛠️✅

Used to break loose shower control assembly which had seized onto the receiver spline. Couple of applications over about twenty minutes did the trick. Makes whatever your using it on slippery like soap. Heavy chemical odor, so make sure you environment is well ventilated.

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.
