Anyone used "Back 2 Brass"?

Looks like a miracle worker, which makes me skeptical, but curious to see if anyone has any reviews...very few reviews online. Sinclair is one of the few that sells it.

Back 2 Brass

The cleaner may be safe, but it is the lead, carbon and primer residue that is hazardous to your health and it will still be present. Just smart marketing speak....

Agree with that...I am more interested in whether it will clean brass well than whether it is 100% non-toxic.
