Removes stains! [SEP] Looking at the ratings, I guess I like this product more than others do because I purchased it to remove stains on my veneers, and not to whiten my teeth.  I love that's it's gentle, yet removes stains well.  Honestly, my only complaint is that it's difficult to rinse out of my Spinbrush toothbrush.  I ended up buying a Spinbrush to use solely with this activated charcoal gel.  Problem solved!
