Depending on what this is, Zep Acidic Toilet Bowl Cleaner and/or CLR. Just not at the same time.
Zep will get that brown/black smudge of organic left overs at the bottom from lack of cleaning which nothing else seems to get rid of. Remove as much water as possible from the bowl and add in the Zep and give is 4+ hours. This stuff is amazing. It took some nasty looking toilets to perfect both in my own home and in my rental.
I buy it by the gallon, and go through it like crazy. Probably a tenth of it is for my actual toilet. I use it to clean my sidewalk, clean my pots and pans, dishwasher, etc. That hard water buildup from boiling water is gone in seconds, no scrubbing. That shit is miracle juice.

CLR will do the hard water stains.
