The original Wet & Forget concentrate is the ultimate outdoor moss, mould, lichen and algae remover that is safe to use on any exterior surface. It kills problem spores and helps stop premature regrowth of unwanted biological growth.
The original Wet & Forget concentrate has a unique combination of biodegradable selective fungicides to target moss, mould, lichen, algae, and general biological growth. When diluted with water and applied to a dry surface, it immediately attacks the growth. These fungicides work in conjunction with a carefully selected range of surfactants to help loosen and lift biological growth, and then Mother Nature takes over. The weathering process gently removes the decomposing growth over time without damaging the surface it has infested.
