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

I've compared this to many other similar products and I have to report that this one stood out to actually do what it claims. My best results were to leave the product on over night for stubborn, ver rusty and corroded nuts/bolts and anything that is frozen due to time and related oxidation.It worked better than most other products. Highly recommend.

I used this to break a 15/16 lawn mower nut loose. Previously used heat, an impact wrench and even tried a break bar. All everything did was round the nut off, so I bought a can of this penetrating oil and an extractor bit. I tried the extractor bit first, without the oil to see if that was all it needed. No luck, so I sprayed about a 1 second burst of this onto the nut holding the blade. I waited about 2 minutes, maybe a little less, put the extractor bit back onto it and it came right off. I put all the backstory in there so that you can see it was this that made the difference on whether or not that nut was coming off without being cut.

I absolutely love this Free All Rust Eater Deep Penetrating Oil! It's a game-changer for tackling rust and making maintenance tasks a breeze. The 11 oz aerosol can delivers powerful penetration, making it perfect for loosening stuck parts and preventing future corrosion. Highly recommend this amazing product for anyone dealing with rust issues! 🔧🌟

Works well.

Replacing o2 sensor on Jeep Compass. Wouldn’t budge. Ordered this stuff. Success!! I sprayed it from the top and it still seemed to penetrate the threads of the sensor.

Plumber said to buy it, its works. He was right lol

I used this product on hinges on my cast iron smoker that were rusted shut and well and behold after a few applications I was able to get these hinges to cooperate again. Does what it is supposed to do.

tried to use it for days on stuck valve, didn't work for me - had to have the valve replaced. Might work for one that wasn't stuck as long. The smell was very, very, very strong.
