Description

D/2 Biological Solution is a safe, effective, and easy-to-use liquid that removes stains on surfaces and architectural features caused by mould, mildew, algae, lichens, and air pollutants.

Made in the USA and tested and used by the US Department of Veterans Affairs and the US National Park Service, D/2 is a biodegradable cleaner that is pH neutral; contains no salts, bleach or acids; and does not leave behind salts that can damage stone the surface.

Application

D/2 can be used on all kinds of masonry surfaces, including brick, stone, concrete, stuccos and plasters, terra cotta, monuments, sculptures, and headstones. It is also effective for cleaning wood, vinyl & aluminum siding, fibreglass, metal, painted surfaces, and canvas.

A contact time of only 10 to 15 minutes followed by scrubbing with a soft bristle scrub brush will loosen most biological and air pollutant staining.

  • Always do a spot test sample before proceeding with a project.
  • Works best when air and surface temperatures are 10°C (about 45ºF) or above.
  • Use undiluted for the best results.
  • In the event of excessive plant exposure, rinse all plants and water in all planted ground areas.

Shelf life is about 5 years.

Best RV cleaner ever

How many times have you put your awning down on your RV only to see the black mold all over it. This solution will not only clean it off easily, but the next time you use it whether it's next year or next week it will still be beautiful and white.

Great product!

Used this on a very old marble head stone of my great grand father. Great results.
