D/2 Biological Solution Eco-Friendly Outdoor Cleaner in gallon size is a biodegradable and pH neutral cleaner specially formulated to remove environmental pollution, dirt, and staining from biological soils such as mold, mildew, lichen, and algae from indoor and outdoor surfaces. D/2 contains no salts, bleach, or acids and is highly effective for removing stains caused by biological growth on surfaces including marble, granite, limestone, masonry, concrete, wood, canvas, and vinyl & aluminum siding. It’s best known as a gravestone cleaner, yet it won’t damage glass or metal.  In fact, it won’t hurt plants either.

D/2 is the only product developed for conservators by conservators. It has been successfully used to clean millions of buildings and monuments, from the White House to Arlington Cemetery. It was tested in a 6-year study and is now specified by the Department of Veteran Affairs National Cemetery Administration.

Treatment and Maintenance Program: After initial treatment of surface, a light spraying once per year will help maintain a clean, stain-free surface.

Note: Heavy biological deposits may require repeat applications of D/2 cleaner to achieve complete cleaning. Alternatively, heavy growth can be detached by manual scraping using wooden or plastic tools immediately after application.

How To Use:  Apply D/2 with a brush, roller, or sprayer.  Allow the undiluted D/2 to remain on the surface for 5 to 10 minutes.  Apply additional D/2 to maintain a wet surface.  Scrub the surface thoroughly with a non-metallic, short fiber scrub brush.  Lightly mist with water and continue scrubbing.  Rinse thoroughly with fresh water using a hose or sprayer.
