For removal of moss, fungal and lichen Bio-Shield works very well as and out door cleaner and is the most cost effective at 85cents per litre. I have been using it commercially for 26 years and found it is effective in cleaning up any exterior surface that is exposed to rainfall. Once the affected surface has been cleared of lichen, moss or fungal growths just respray it at the first sign of regrowth and it will stay clean. Its only available at www.bio-shield.co.nz
