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

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.

This is my second order for this product, and I really like it. I use it often for stuck bolts and such, and it seems to have a really good lubricating quality as well. I live in the south, so salt corrosion is not an issue, but we do have our fair share of rusty hardware, and this seems to work well. I have used PB, and a couple of others, and I think this is better. I rank this one right up there with Kroil.

This stuff is incredible. It works so well I could not believe it. I have never seen anything cut rough so fast and break bolts loose a definite must in your garage.

It works very well. I would definitely order again

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.

Don't be fooled by pic. It's a very small 1.5 oz bottle. However, I was doing a lot of repairs and had several 'frozen' nuts and bolts that other products were not effective on. This stuff works! It only takes a small amount and let it set and soak in for 5-10 minutes. I'm very glad I have it now. Hate drilling out those broken bolts.

Dual-bladed spinner stopped spinning after multiple applications of 3/1 oil. Free All seems to be working well after multiple applications. Appears to have reduced rust which was obviously the problem.

For freeing rusty nuts, bolts, etc. this product is hands down the best lubricant I’ve ever come across. The only problem I had was after using 1/4 of the can the aerosol pressure went flat so now I’m stuck with 3/4 of a can that I can’t spray out. Maybe the one I got was just a dud so I’m gonna order another one and hopefully I don’t get that problem again.
