Before we had to evacuate I did a little experiment with the mould. I sprayed some of the walls and doors with VRM Biologik® Mikro® Clean Ultra, a non-toxic, chemical free cleaner, to see if it would protect the walls from mould. I have returned today to check it out. Pictures of where sprayed and where not sprayed. Mould = not sprayed.
