Review on Supco MO44 Buster Liquid Penetrating by Owen Blanco

Excellent product. Used it on the center assembly of our 11 year old washing machine. Unfortunately, the lock nut stuck to the knot underneath. The Rust Buster liquid removed all of the surface rust, but after six hours of screwing in the right direction for this reverse-thread nut, it wouldn't come loose, so I sawed it off with a hacksaw. After that, repair was easy (although we never fixed the leak we were trying to fix and ended up buying a new washing machine). I was disappointed in the end, but I realized that the rust remover wasn't the problem - it actually made the entire assembly clean and rust free.
