Information from Norwex:
I have been using this system for about a month. It works really and has given me some peace of mind. I used to use Comet and then Comet with Bleach. I would scrub the toilet with Comet. Then I would flush and run the brush under hot water and scrub the toilet again in hopes of removing any residue. In 10 years I have only seen my cat drink out of the toilet once but that was enough for me to be extra cautious. The Sanira System from Norwex works better than what I used to use. This brush gets under the rim better. In fact there were sometimes pieces of black gunk set loose from under there by this brush in the beginning.
