I used diluted Zoflora in the old house on terracotta tiles and the whole house smelt beautiful. In the new house made a big mistake, huge - got shiny charcoal tiles in the kitchen and hallway. They look wow when freshly vacuumed and mopped, but the tiniest fluff or drops of water makes them look dirty pretty much immediately. It is what is for the next 20 years, lesson learnt. I have been cleaning them with a flat microfibre mop with warm water so far, as Zoflora leaves a cloudy film. Would be grateful for supermarket cleaners that smell lovely and will not leave a hazy residue. Not wholesome enough for lemon juice and vinegar.
