It goes without saying that knowing how to clean a grave marker properly can go a long way in extending the life of a memorial but how does one clean a stone? Although the cleaning of a gravestone may seem quite simple, this is not always the case. Every time a historic stone is cleaned, some of the stone’s surface is removed in the process. Clean it too often, and all the inscription and details may be washed away! Bob Young, administrator of the Evergreen Cemetery and owner of a cleaning and restoring gravestone company, will lead participants on the proper procedures for cleaning a gravestone. This course will be held at the Historic Evergreen Cemetery, where Mr. Young will give demonstrations.
