D/2 Biological Solution

D/2 Biological Solution
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 was developed by conservators who know the damage that can be done by cleaners containing acid or salts. Our product has been specially formulated without these harmful agents. D/2 is pH neutral quaternary ammonium solution with surfactants that help carry surface contaminants away. No other solution is more trusted by architectural and monument conservators.

D/2 Biological Solution is effective for removing harmful biological and air pollutant staining from many building materials.
