This product came highly recommended for cleaning tombstones. As it turned out it was great (in my experience). For years I have used several products and a number of home made blends of individual products to clean stones. The D/2 Solution has consistently worked better to provide a good cleaning without leaving residue or staining on the stones.
Probably the most important aspect of this product is that there do not appear to be any negative or any downside to using the D/2. Other products and materials I've used all seem to have claims of damage to tombstones either immediately or over time with reuse. I have been very careful using any of my various concoctions, and have seen no degradation. However, I don't want to realize at some point that I've damaged any stones.
None of those claims with the D/2 performance. The only issue I have is the cost. Wish I could find a more economical source.

This product works wonderfully. We use it to clean 100 year old grave markers. Too bad it is so very expensive to use.

Introduce curator of cemetery to the solution. He said he is going for a 55 gal drum. Results were as advertised.

I have NOT bought this yet through Amazon but am about to. I witnessed a demonstration last week. It works unbelievably well and is supposedly not harmful to marble. Someone complained about it not working on their flagstones. NOTE: The person showing me this product said it had not worked on removing mold from a highly polished flat grave marker. Apparently the mold was deep under a slick polish which would need to be scrubbed or abraded to penetrate. The guy demonstrating it (not a salesman, just a man restoring the cemetery) said he would probably have to scrub that particular grave stone a lot. But 99 out of 100 markers were like brand new. He sprayed it on or poured it on and either let rain wash it clean weeks later, or he would lightly scrub with a bucket of water.
