Description aside it stained my hand deep blue.  This is no natural substance.  This CAN’T be good for the environment.  (Yes, what you flush ends up in the bow river eventually.)

Want a clean toilet without harsh chemicals?  I’ve heard baking soda and vinegar work wonders. (I think they even produce a bubbly cleaning action so you can “see it work” as the toilet cleaner my mom used to use claims is quite exciting.)
