My toilet pan has a stain below the watermark that neither bleach nor

what stronger products are easily available that will remove it?
You need hydrochloric acid. Probably the strongest supermarket cleaner
with highest concentration of HCl is Harpic 10x, about a quid a bottle.
The stain is basically discoloured calcium carbonate.
Could it not be removed mechanically by scouring ?
Angle grinder!!!!
