About

D/2 Biological Solution is a biodegradable, easy to use liquid that removes stains from mold, algae, mildew, lichens and air pollutants. It is effective on marble, granite, limestone, brownstone, travertine, masonry, terra cotta, concrete, stucco, wood, and other architectural surfaces including monuments, sculpture and headstones. A contact time of only 10 to 15 minutes followed by scrubbing with a soft nylon or natural bristle brush will loosen most biological and air pollutant staining.

D/2 Biological Solution is effective for removing harmful biological and air pollutant staining from many building materials including masonry, marble, granite, limestone, brownstone, travertine, terra cotta, concrete, stucco, wood, canvas and vinyl & aluminum siding.

NCPTT study recommends D/2 for cleaning government headstones.

Researchers studied five different cleaners on stones located in five different climates at locations across the United States. Microbiologists at Harvard University evaluated samples for regrowth of microorganisms including bacteria, fungi, and algae. D/2′s quaternary ammonium solution came out on top!

D/2 awarded Veterans Administration contract to supply cleaner for over 3.5 million headstones.

The U.S. Department of Veterans Affairs is tasked with the regular maintenance of more than 3.5 million white marble headstones nationwide. Based on recommendations resulting from a six-year study conducted by the National Park Service, D/2 has been selected as the preferred cleaner for maintaing these memorials to our country’s fallen heros.

Civil War monuments get D/2 makeover at Chickamauga battlefield. A six-person preservation team with the National Park Service has been working its way around the Chickamauga and Chattanooga National Military Park giving its Civil War monuments a spring cleaning. The crew, which works out of Frederick, Md., and travels the country to clean monuments, will work at the park for about three months. The group uses the environment friendly cleaner D/2 to clean the structures.
