I finally got a little (120ml) bottle of Zoflora from Poundland last week, having been looking when I remember since it was recommended on here. It says dilute 1:40. What do you Zoflora users do then, please? Do you make it up with water in a spray or other bottle to keep in the bathroom, say, and use ad hoc like any other disinfectant product? Or do you just make up small amounts at a time to use all at once? Any tips?
