Our last toilet seat developed horrible yellow stains under the seat. Impossible to shift. Just had a lovely new bathroom put in and the brand new toilet seat is getting the same thing. Yes, I have boys who wee everywhere.
(Some one in a bathroom showroom once told me it was due to not leaving the seat up when using Harpic, but that doesn't add up as it is more yellow in some places than others).
How do I get rid of these disgusting yellow stains? Steam cleaning, cream cleaners and magic wedge of foam from Lakeland have all failed. I've never noticed this at anyone else's house, so where am I going wrong?
