The best rut remover and lube I’ve ever used

Good stuff and works great.

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.

This stuff works amazingly well. Smells bad. The nozzle quit after a few uses. Other than that, a fine product.

Best stuff on the market! I've been wrenching for over 50 years. This is the best rust buster I've ever used.

I’ve used many different penetrating oils. Stuff works the best. Use it everyday at work and at home. Used many cans and never lets me down. Love this stuff.

Free All is a great product! I learned about this stuff from a few old timer mechanics years ago. It was getting harder to find so I was excited to find it again! Hands down one of the best penetrating fluids I have found in my 25+ years of experience! More than good enough for commercial use. Would recommend for any project!

Helped me tons with my rusted out 77 Chevy. The hood sits like new now and latches. And the rusted lights came off so much better.
