D/2 Biological Solution is specially formulated to remove environmental pollution, dirt, and staining from biological soils such as mold, mildew, lichen, and algae from indoor and outdoor structures. Staining and soiling caused by mold, mildew, algae, lichens and air pollutants contribute significantly to the degradation and disfiguring of many types of construction surfaces. D/2 can be utilized to safely resolve this problem on all wood, stone, masonry, metal, vinyl, and roofing surfaces. D/2 works best when used at 45 degrees F or above.
