DIY vs. Professional Headstone Cleaning: When to Call in the Experts

Some markers are safe to rinse yourself. Others need a conservator. Here is how to tell the difference before you pick up a brush.

What this article covers

• Identify the soiling before choosing any method
• Sound modern granite tolerates a careful DIY rinse
• Marble, sandstone and historic stone need a professional
• Any crack, flake or wobble means stop immediately

Every memorial is different. Stone type, age, exposure and cemetery rules all change what is safe to do. If you are unsure at any point, stop — a stone can be cleaned again next month, but damage caused by the wrong method is permanent.
