Headstone cleaning must take into
consideration the operational
standards set forth by the National
The following standards are among those designated for headstones:
•Headstones, markers, and niche covers are clean, free of debris and
•Headstones, markers, and niche
covers are not damaged by cemetery operations (e.g., internment, grounds maintenance, headstone, marker, niche cover, maintenance, facility maintenance operations).
Maintenance practices must have an eye toward the future. Many cleaning methods may be able to remove soiling from headstones. Some will be more effective than others. But the long term effects must also be considered.
Anyone developing a cleaning method must look at the soiling agent to be removed, the potential threats caused by the soiling, and the possible unintended results of cleaning. NAPSNCPTT/DVANCA/05-23-2011.
