Hi all, Sorry this post is a little grim. The toilet has a growing orange stain which I cannot seem to get rid of on the part above where the water flows from, I can't really describe it but please see the image link imgur.com/a/CHaINPi (clean toilet don't worry). I have tried baking soda, bleach and vinegar leaving it overnight, which hasn't worked and I really don't know what else to do. Any help/suggestions would be greatly appreciated!
