Break Free is very good. It contains anti-seize properties along with a capbaility to lubricate. It's works extremely well in cleaning guns (especially those hard to reach spots). One of its draw backs is that it attract dust, sand, etc....
Sentry Solutions Tuff Cloth and Glide are more of a complete lubrication/protective package. It doesn't attract dust, sand, dirt, etc....... It can also be used on different materials (woods, metals, etc...)......
I've tried it all and the best stuff is the "Tuff" stuff...
