D/2 Biological Solution Reusable Spray Bottle, 32 Fluid Ounce

Works very well removing the black stains from trees and likens that grow on the granite headstones. 2 ways to apply it, first one is just spray it on and then let the rain do its job or spray it on and use a brush to scrub it and then rinse it off with water and then reapply it again and let the rain rinse it off. It doesn't remove everything instantly but will make the stone look new again after several weeks. I had a friend who owns a monument company recommend this to me. It works well.

The chemical used in this item really did help me clean seven graves. Several of the graveside were at least 30 years old, black and moldy. They came really good and clean. I will share pictures so you would be able to see. I highly recommend this product.

Wonderful company to do business with. I really appreciate the personal touch added with the handwritten thank you note. My 88 year old Grandfather wanted to clean headstones of his Mother and Brother that needed A LOT of TLC. We sprayed it, walked away and came back after a good rain. He was pleasantly surprised at how well it worked! It brought tears to his eyes. I just bought a lot more to make them sparkle for him! The product was so easy to use! It didn't damage the headstone's finish. My favorite is that it is NON-TOXIC! No chemical smell or lingering offensive smells! It has a clean smell that you don't mind! Thanks again!

D2 Cleaner is made to keep Grave Stone markers clean and readable for the future. For the Past 4 years, we have been using D2 Cleaner on our Family's Grave Stones. The results are increasingly impressive!! These Grave Markers are in a location where they definitely get 4 Season Weather, including rain and snow in the winters. Even the old bronze grave markers were very readable in our photos taken this year. The Granite Grave Stones shine like they have been professionally polished! Thank You Walmart for offering D2 Cleaner for sale to your customers! It is the Best!!

This stuff really works! I just used a soft brush to clean off the monument, which was still stained with dirt . Then I sprayed it with D2 and went back each week to check it out. Nature worked with it and it took 4 to 6 weeks and it was beautiful. I will buy this again for sure.

This product is exceptional. I spayed it on my brother's headstone and waited 10 minutes. It worked in a lot less time. The lichen started falling off almost immediately. Now that it's "clean" I am going to spray again the next time I'm there for maintenance.

I have used D/2 a few times for cemetery marker cleaning and this product does not harm the marker. It also deters regrowth of bacteria for a time on the marker.

I use this on a 1960 tombstone. I sprayed it on and waited for natural elements to take place. The company that sells the product actually wrote Thank you on my invoice.

Cleaned a decades old stone that was embedded with grime. Spray, wait a few minutes then brush with a nylon scrub brush. A funeral director commented on how clean it was and asked how it was done. An impressive product.

It worked great on our granite bench in our cremains garden at church. It was looking bad ...Turns out it was simply mold growth. Easily removed it . Our bench looks great!
