My wife and my sister wanted to do a project for the community, especially with Memorial Day coming up. My wife purchase a small sprayer bottle to use as a “trial-sample”. We haven’t used it long but saw immediate effects on the headstones that we used it on. So far, we have only scratched the surface of the veterans’ headstones and have posted pictures on facebook. The community is going wild over the short-term results and we will continue to update with the continual long-term results.

I have used this to clean statues around town that had many years – decades of pollution and lichens. The results are a amazing and did not harm adjacent plants. I applied as directed and scrubbed moderetly. The results were fast. I did lightly apply additional cleaner and over the next week or so it continues to clean. Highly recommend.

I’ve used D2 Biological Solution on 50+ monuments in my old cemetery while I was their sexton, & all I can say is, WOW what a difference. I would highly recommend this product if you were cleaning your families headstones or taking up the business of doing the same. It’s an amazing product.

Used it to clean a former President and First Lady gravestones. Danby White marble. North sides were entirely green. Now, more white than they have been in decades.
I would caution that white marble will turn an orange color when used. As if someone poured rusty water over it. Don’t panic, if you scrub, it’ll go away quickly. If you spray and walk away, it might take a day or two. Great results though!
