The most effective time to clear your moss is when it is the most active; therefore when it is growing. It is best when surfaces are dry and during dry, mild weather. Late winter, early spring and the Autumn months are the most active growing periods so, especially if using a cleaning treatment such as Baticlean CR, this is the most effective time to start your cleaning.

If you are using one of our cleaners for stubborn or heavy staining, such as Batiface or Batifort, then the time of year is less important as the product is not so reliant on dry or mild weather.
