Absolute mess
I could not tell you if this works overtime because I don’t have 20 minutes to clean up the disaster that it makes all over your bathroom. This product needs to be re-thought as far as how it’s packaged. Maybe a container where you can sprinkle the powder on toothbrush? Not a container that you open and black powder goes flying everywhere.  Packaging definitely needs to be re-thought. It makes an absolute mess of your bathroom. Not a fan.
