Free All Deep Penetrating Oil Rust Remover, Loosen Rusty Nuts & Bolts, Screws, Clamps, Pipes, 11 oz. Aerosol, 2 Pack

I used this on 9' tall, heavily rusted, heavy steel door latches and hinges that always took a lot of effort to open and close. A week into spring, I opened these taking most of what I could do to unlatch and lean heavily into the doors to open and close. I used this product (nearly half a can) on all moving points. The next time (just a couple days later) I opened them a gust of wind silently blew one shut. Having previously (last summer) tried two other name brand products with very little, if any, improvement, this is just amazing! I thought this product was a bit expensive but after seeing it actually do what it claimed, worth every penny. I didn't actually see it eat any rust but the years of rust seizing these doors did seem to evaporate! If you have rust issues this is a product to try. I ordered this months before I received it. Well worth the wait.

Best I’ve ever used at our place on maintenance

I used pb blaster for many jobs, I was doing interior and suspension work, and still stripping screws they were so frozen. A friend gave me Free All. I resprayed the frozen screws, and I am not exaggerating one bit, after a minute or two every screw or nut I sprayed came off with ease, it's unbelievable.. this stuff works awesome..

Decent, but no better than other products I have used

I grew up using WD-40 and couple years ago switched to this for rust issues. I have several Harley’s I’ve collected over last 30 years and have a 2000 soft tail that has some rust issues. This lubricant is amazing. Doesn’t completely remove but definitely helps .
