We had two brand new toilets tht quickly began a discoloration at the
water line in the bowl. We tried leaviang bleach in overnight but it
didn't work for us initially. To finally get rid of it we used a
commercial acid-based toilet cleaner that completely eradicated it.
Now we drop in a cholorine tablet into the tank once a month and the
stain has never occured again.


Flush the toilet, add 1/2 cup bleach, then lay a layer of TP all around
on the bowl so the lower edge is in the water, over the stain. Flush it
in the morning.
