Treatment and Maintenance Program
After initial treatment of substrate, a once-a-year light spraying will help maintain a clean, stain-free surface.
NOTE: Heavy biological deposits may require repeat applications of D/2 to achieve complete cleaning after detachment. Alternatively, heavy growth can be detached by manual scraping using wooden or plastic tools immediately after application. In the event of excessive plant exposure, rinse all plants and water-in all planted ground areas contacted by D/2.

We had a small bottle that we used with great results. Now we want to clean some other stones. We care about these old memorials and are happy to find a product that doesn’t harm them.

I have successfully sprayed this on white marble tombstone covered with black mold & after 2-3 sprays & no rubbing stone was all white! I also spray it on granite stones & my pine deck boards to prevent/eliminate green mold with no scrubbing.

My husband and I purchased this product to clean his parents monument at the cemetery . Their stone got to a point where you couldn’t even read the names on it. D 2 had been recommended to us , so we figured we would give it a shot.
We went to the cemetery with our D2, water mist bottles , and a scrub brush, and were AMAZED with the results. After many years of mold and blackened out lettering, our parents stone. came back to life. It’s like their honor was given back to them. Such a wonderful product. We would definitely recommend it !!!!
Thank you D2 !!!!!!

I learned about D/2 when it was provided by the graveyard where my parents are buried. I could see it worked so well, that I ordered my own gallon to use on flower pot stains on my patio and on mildew around the front sidewalk of my north facing townhouse. It’s a great product!
