How to remove central heating draindown stain from ceramic toilet?

Jan 21, 2006 3 Replies

My plumber drained my central heating system into my loo today and now I have a dark stain over the white ceramic.



How am I best to remove this stain?



TIA, dave.


Use a few bottles of coke or throw in a packet of denture cleaning tablets! Both work very well.

Don't pay him until he fixes it.

It's probably just stained a thin limescale coating, in which case any of the toilet limescale removers will remove it.
