About D/2
D/2 Biological Solution removes organic growth from most surfaces. It lasts 5 times longer than bleach, peroxides and powerwashing. D/2 is safe to use near grass and most landscape plantings.
Growth of bacteria, fungi, algae, lichens and mosses contributes significantly to the degradation of many types of construction materials, and can be disfiguring. D/2 can be utilized to control this problem on outdoor sculptures, monuments, decorative fountains, gravestones, and tombs. Biological growth found on some individual building features (such as parapets and zones of ground contact) or materials (such as stucco) can also be treated with D/2, although it is not a general purpose architectural cleaner.
