D/2 Biological Solution is effective and safe for a wide range of masonry and architectural surfaces, including render, coloured render, concrete, brick, cast stone, aluminium, vinyl sliding, canvas and wood. Those in favor of this product site the previous reasons and back that up with the manufacturer’s claims. D/2 can be safely used to remove dirt, soot, pollution, and biological discoloration from most masonry surfaces. By using D/2, you are cleaning the organic material off the stone and in so doing, you may reveal damage to the stone you wouldn’t have otherwise seen.But do document the stone condition, taking close-up photos at many angles (you may need this for insurance purposes). Why use more D/2 when I could use some water, a tampico brush and a little elbow grease to cut through the worst dirt?
