Headstone cleaning and care
Headstone cleaning should be gentle and matched to the stone, finish and cemetery's care requirements.
A careful guide to headstone cleaning, routine care and when to ask a stonemason or cemetery before using a cleaning product.
Check the stone before cleaning
Granite, marble and other stones can react differently to cleaners and scrubbing. First check for cracks, flaking, loose lettering, repairs or a fragile surface. If the stone is unstable or damaged, do not press on it; contact the cemetery or a qualified memorial mason.
Ask the supplier or cemetery whether they have specific care instructions. The Natural Stone Institute's general natural-stone guidance recommends gentle cleaning practices; its guidance is not a substitute for advice about a particular grave marker or local cemetery rules.
A cautious routine for light surface dirt
Do not use household chemicals or scrape biological growth from a fragile memorial. Some stains and growths need specialist treatment; aggressive cleaning can cause permanent surface damage.
- Remove loose leaves or dust by hand without pulling at lettering or decorations.
- Use clean water and a soft, non-metal brush or cloth only if the surface is sound.
- Test any approved cleaner on a small, inconspicuous area first.
- Rinse gently and stop if the surface changes, flakes or becomes loose.
- Avoid acids, bleach, wire brushes, abrasive pads and pressure washers unless a qualified stone professional specifically approves them.
Protect lettering and attached plaques
Avoid scrubbing directly over paint, gilding, photographs, repaired lettering, adhesive-backed plaques or a QR code. If a QR plaque is installed, follow its product care instructions and do not apply solvents around it.
Take a clear photo before and after any maintenance. If you notice a change, stop and ask the cemetery or stone supplier for help rather than trying a stronger chemical.

Frequently asked questions
Can I use bleach to clean a headstone?
Do not use bleach unless the stone supplier or a qualified conservator specifically confirms it is safe for that exact stone and finish. A wrong cleaner can damage stone or lettering.
Can I pressure-wash a grave marker?
Avoid pressure washing unless a stone professional approves it. Forceful water can worsen cracks, loosen lettering or damage a weak surface.
How often should a headstone be cleaned?
There is no universal schedule. Follow cemetery and supplier guidance, and clean only when needed using a method appropriate for the material.
Who should clean an old or damaged memorial?
Contact the cemetery or a qualified memorial mason or stone conservator. Do not attempt repairs or deep cleaning on a loose, cracked or flaking stone.
