How to Use D/2 Biological Solution to Clean a Gravestone

This video shows step-by-step how to use D/2 Biological Solution to clean a historic gravestone or monument.  Sometimes lichen & algae on a historic monument can be aesthetically pleasing, so the first question is why even clean the monument?   The simple answer is that the mold, mildew, algae, & lichens are feeding on the stone and thus, actually destroying the monument.  The next question to ask is whether the monument is in stable enough condition to clean.  As you will learn in this video, the first rule of cemetery conservation and preservation is do no harm.

Enjoy!  And let us know if you any questions.
