Sorry about the tmi....
... But DH is pretty grim on the loo. He just seems to leave marks all down the sides, and along the pan under the water extending down the ubend. Also, specks and spots all over the porcelain. Too much rich food, or, I don't know. Vom.
Please talk me through your top tips of how you clean the loo. Am NOT a fan of toilet brushes standing by the side of the loo, because surely a good weekly clean with the right things should do the job??
