How To Clean A Headstone Without Causing Damage
Cleaning a headstone is a meaningful way to honor a loved one, but if you use the wrong tools or techniques, you could accidentally cause permanent damage. This guide on how to clean a headstone without causing damage walks you through safe, effective methods to clean a headstone the right way—without risking cracks, erosion, or fading inscriptions.
Why Proper Headstone Cleaning Matters
Gravestones are made from porous materials like granite, marble, limestone, and bronze. Over time, they accumulate dirt, moss, algae, and other growths that can break down the stone’s surface. Using harsh chemicals or the wrong brush can wear away inscriptions or weaken the material itself. Proper cleaning is about long-term preservation, not just appearance.
What You’ll Need
- A soft-bristle nylon brush
- Two buckets: one for clean water, one for rinse water
- A non-ionic or pH-neutral cleaner (like D/2 Biological Solution)
- Clean rags or sponges
- Gloves (optional but helpful)
Avoid anything abrasive. Wire brushes, power washers, bleach, ammonia, or household cleaners can all cause damage.
Step-by-Step Guide
- Inspect the stone. If it’s cracked, flaking, or loose, stop. It may need professional restoration.
- Rinse the surface. Use clean water to soak the headstone completely.
- Apply cleaner. Spray or gently sponge on a pH-neutral solution.
- Scrub gently. Use a soft brush with light pressure, working in circular motions. Always start at the bottom and work upward.
- Rinse thoroughly. Use clean water to remove all residue.
- Dry if needed. Blot with a soft towel or let it air dry.
What to Avoid
- Never use bleach or acidic cleaners
- Skip abrasive pads or wire brushes
- Don’t clean in freezing or very hot weather
- Avoid pressure washing or drill brushes
Aftercare Tips
Once cleaned, most headstones don’t need another deep clean for at least a year. In between, keep leaves, grass, and debris away from the base. A regular light rinse is fine if you’re local.
If the stone needs more care—like mold removal or layered biological growth—consider a professional headstone cleaning service that follows U.S. National Cemetery Administration guidelines.
What’s the safest way to clean a headstone?
Use clean water, a soft-bristle brush, and a pH-neutral cleaner like D/2. Avoid anything harsh or abrasive.
Can I use bleach or household cleaners to clean a headstone?
No. Bleach and similar products can cause permanent damage. Only use cleaners specifically made for gravestones.
How often should headstones be cleaned?
Once a year is typically enough. Too much cleaning can wear away the surface.
What if the stone is damaged or unstable?
If it’s cracked, crumbling, or leaning, don’t attempt to clean it. Call a preservation expert.
Is it okay to clean headstones at any time of year?
Avoid extreme cold or heat. Spring and fall are ideal for headstone maintenance.
