Gravestone Cleaning : To clean or not to clean, that is the question? One of the most often asked questions regarding historic gravestones is ,”how do I clean this stone?”.
Unfortunately, there is no one correct answer. The first rule to follow is to use the gentlest means possible. With this being said a highly deteriorated gravestone should be left alone. Many well intentioned cleaning efforts have defaced or destroyed weak and fragile stones.
Since it is easily possible to do significant damage in a cleaning effort, first we will cover the most common errors.
The following cleaning techniques have no place in an historic graveyard!

- Do not use any type of acids or acid based solutions.
- Do not use any kind of abrasives, especially sand blasting.
- Do not use metal or wire brushes, leave them in the garage.
- Do not bleach or any other household cleaners, leave them in the kitchen!
- Do not attempt to clean any stone that appears to be flaking, crumbling,or weakened in any way.
