Quote:The grout between our tiles was a nice cream colour but it has become very dirty. I've tried everything to clean it but nothing works. Is it necessary to remove the old grout it I was to re-do it with a more workable colour?
I've never found any of the whiteners or so-called miracle cures to work. When faced with a similar problem at home, it became yet another use for my Fein MiracleTool (sorry, MultiMaster) and I used the fine diamond blade to quickly remove the old grout.
