D/2 is not just used for cleaning stone surfaces, here's what it can do on wood!
"Using the results of her testing, Kirschner created an affordable three-step process for cleaning and protecting the wood: First, spray the siding with D/2 Biological Solution, a biodegradable liquid that cleans the wood and removes mold, algae, and other biological growth. (“This is preservation dream stuff,” Wilson says, citing its environmentally friendly ingredients and its ability to clean and remove stains.) Then apply Bora-Care, a biological deterrent with an active ingredient of borate salts, which keeps wood-destroying organisms such as termites, carpenter ants, and fungi at bay. Finally, brush on TWP 1530, a water-repellent preservative that protects wood from mildew, UV damage, and general weathering, while also aiding in color retention."
