Free All Deep Penetrating Oil Rust Remover, Loosen Rusty Nuts & Bolts, Screws, Clamps, Pipes, 11 oz. Aerosol, 12 Pack

Now this stuff is a life saver and it works really fast apon application. But be aware to never get it near or in your eyes! Not that you want to ! Wear protective safety glasses when using . I was under a car , I sprayed it and got some in my eye by accident. God that sucked! Other wise the stuff is amazing

Great product does a really good job. Great for locks! I highly recommend this product!

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.

It works very well. I would definitely order again

This is some of the best penetrating oil I have used. I have been using it for around 3 years now and find it hard to beat. I used to use Kroil, but it is simply too expensive now. This is a lower cost (although not dirt cheap) alternative to Kroil that actually works. I have tried many other brands over the years but found Free All, tried it out, and was surprised what it can do. It is also excellent at cleaning light rust from tools and guns. I just spray them down sparingly and let them sit a few minutes and then just wipe them down. Rust dissolves and comes right off with no scrubbing or damage to the surface. I also like to use it in my machine shop for the bare metal surfaces of the machinery like the ways on my lathe and mill table. Works great.

Fast delivery. Works great loosened my rusty bolts. Thanks

I didn’t know this stuff existed and it loosens loads of stuff.

Works like and other of the same type. Just smells like chemicals and cost more. I cannot recommend this because of the price when cheaper penetrating oils have the same results.
