Headstone Cleaning: Sergeant Frederick Held

On May 1, 2021, we were given the opportunity to provide service to the memory of Sergeant Frederick Held of Company B, 56th Ohio Infantry Regiment who is interred at Greenlawn Cemetery in Portsmouth, Ohio.

Below is both a time-lapse video of the cleaning and a side-by-side comparison of the marker before cleaning and immediately afterward. The marker will continue to lighten over time due to the use of the NCPTT (National Center for Preservation Technology and Training)-approved D/2 Biological Solution.
