D/2 Biological Solution has proven to be an easy to use, safe for humans and the environment, and an effective biological cleaner on gravestones of various compositions including marble, limestone, sandstone, and granite. It has shown to be a leader in its field. Thus, I wanted to share my “before cleaning” and “after cleaning with D/2 Biological Cleaner” photographs of the Harvey Limes stone that was cleaned in July, 2015.
I like to spend time researching products and reading reviews and testimonials, and hearing from experts in a field who have used products. So, I was confident before I began that D/2 would be effective and safe in all aspects. I still wore my plastic gloves and donned a face mask “just in case”, but they may not have been necessary. I followed the instructions also provided by the manufacturer to be sure I was applying “D/2” properly; always a smart thing to do!
It must be remembered that not every gravestone truly requires cleaning. Each one should be properly assessed before embarking on any cleaning. Distilled water is also recommended for washing and rinsing.
We know that NO power tools should ever be used on gravestones to clean and/or “polish” them; nor are power washers safe for use on a gravestone.
The best way to learn how to properly clean gravestones is to attend hands-on cemetery presentation workshops conducted by instructors who are known to use only approved methods from such organizations as the National Park Service, and the Association for Gravestone Studies. They subscribe to using Do No Harm practices.
The NCPTT of the National Park Service will be holding a Cemetery Preservation Workshop on September 10th, 2015 in Paducah, Kentucky, if you wish to learn from Jason Church of the National Park Service, who is conducting the workshop, please check out the link above to learn more details.
