Free All Rust Eater Deep Penetrating Oil,11oz Precision Straw, Loosens Rusted Bolts, Nuts, Pipe Connections & Locks, Industrial-Grade Rust Remover, Silicone-Free Formula, Safe on Paint & Plastics

I had never heard of this stuff until one of our mechanics recommended it. We had a lever that was sticking on a forklift. I couple shots using the included straw helped loosen it up again. My coworker even sprayed it on the front of the forklift where the forks slide across. He didn't tell me and when I went to adjust the position of one of the forks it took no effort for it to slide. I now have a can at the house for those hard to move bolts and it penetrates and works well.

It is Free-All, it just works. Almost as good as Kano lubricant at a much better price point. Spray it on let it sit awhile; stuck bolts jump out of their rusty graves.

Okay, I’m impressed. The iron cap on top of a two inch diameter, 15 foot high pole had been there for at least 25 years. It was rusted shut and no amount of force could budge it. I tried an 18 inch pipe wrench and a huge mallet. Zero movement. And as you might guess, zero fun balancing on a ladder that high up, pounding the large wrench with a mallet. Next was Kroll oil. Tried multiple applications. Tried letting it set overnight. Nope. When that didn’t work, I blasted it with a propane torch for several minutes. I did my aerial ballet with wrench and mallet, both when the cap was hot and again when cold. No success. I was discouraged and ready to admit defeat when the Free All arrived. I bought the precision straw version to help direct the spray onto the threads. The first attempt produced no movement. Thinking I had nothing to lose, I thoroughly drenched the threads with a flood of spray. After two minutes, I tried the wrench and mallet. When the wrench moved ¼ inch, I assumed it had slipped. But no, the cap had turned! I wailed away again and again. Each time, the cap moved a bit more. After a half-dozen blows, I was able to unscrew the cap by hand. Amazing! I have no way of knowing if my success was the cumulative result of all my various strategies, but I know that until I applied the Free All, that cap was holding on like it was welded shut. Just so you know, I have no connection of any kind with this company. I wasn’t paid or compensated in any way for this review. I paid full price, out of my own pocket, to purchase this product. I’m simply a fan of products that work. I’ve benefited over the years from Amazon user feedback like this, so I’m humbly providing feedback in hopes it might help others.

Good stuff and works great.

This review is for Gasoila Free All Deep Penetrating Oil with Precision Straw. It has a flip down straw that lets you get into tighter spaces. Without the straw the product blasts out in a tight stream, so don't expect a mist here. A lot more than you expect comes out. This is a rust eating product. It will not just get in there and help grease things up it will literally remove the rust slowly on the parts it can touch. It may take a couple of applications of the product if there is a lot of rust but this will separate the rust from your metal. This stuff has a heck of a smell to it. It isn't obvious right away but be sure you spray this in a well ventilated area. I sprayed this inside my garage and there was no smell whatsoever at first but after I came back 30 minutes later it had filled my garage and needed to be aired out. Just keep this in mind. I was replacing the suspension of my car and thought this was an ideal time to test this product. I had a few bolts that were stuck due to rust on the back end. I sprayed them down with this product several times and left them overnight. I came out the next morning and sprayed them down again and gave it about 30 minutes to sit. The bolts did not end up coming loose for me. This was not the products fault though, I think it did help some in the end. I ended up having to use some pliers to hold the bushing in place which let the bolt spin free. It was really rusty inside so I have no doubt this product helped. Overall this is a product that does what it says and will eat rust away if you give it enough time to work. I would give it at least a few hours to really get in there and do its thing. If the rust is very deep then do several applications over time.

Works like a champ! Sprayed corroded bolts on the manifold for about 2 weeks, applied some heat and they came out smooth as butter.

Works great . I used this to break loose exhaust bolts . Spray waited 10 minutes and went to town. The best I have used is kimball Midwest this is a close second !

Works like a charm to unfreeze car door locks but don’t overdo it.
