D/2 Biological Solution

Great product. I bought one gallon as a test. Once I saw what it could do on granite, I bought for more gallons. I strongly recommend.

Fantastic product. Cleand up white marble headstones to like new. Very pleased.

Our Cleaning solution for our graveyard stones

D/2 worked great on our gravestones. D/2 was easy to use and worked well. I was a little hesitant about using the material on the stones but tested it first and saw no problems. When done the stones looked great. I ran out of D/2 and will be purchasing more for next year to do more Gravestones.
