How to Clean a Headstone

Introduction

Headstones are exposed to weather, dirt, moss, and biological growth that can obscure inscriptions and cause deterioration over time. Cleaning them properly helps maintain their condition while respecting the material and historical value.

What You'll Need

• Clean water (preferably distilled)

• Soft-bristle brush or natural bristle brush

• Non-ionic soap or stone-safe cleaner

• Spray bottle or bucket

• Soft microfiber cloths or sponges

• Gloves (optional)

Steps

Check the headstone for cracks, flaking, or instability before cleaning.
Rinse the headstone thoroughly with clean water to remove loose dirt and debris.
Apply water mixed with a small amount of non-ionic soap to the surface.
Gently scrub the stone using a soft-bristle brush, working from the bottom upward.
Rinse frequently with clean water to prevent residue from drying on the stone.
Wipe excess water away with a soft cloth and allow the stone to air dry.

Alternative Methods

• Use plain water only for fragile or older headstones

• Use a stone-safe biological cleaner for algae or moss growth

• Lightly mist and brush over several sessions instead of one deep clean

What NOT to Do

• Do not use bleach, vinegar, ammonia, or acidic cleaners

• Do not use wire brushes, power washers, or abrasive pads

• Do not clean cracked, flaking, or unstable headstones

• Do not scrub aggressively or carve into inscriptions

FAQs

How often should a headstone be cleaned?

Most headstones should only be cleaned once every one to two years, depending on exposure and biological growth. Overcleaning can cause damage.

Can I clean any type of headstone the same way?

No. Granite, marble, limestone, and sandstone all require gentle methods, but softer stones are more vulnerable and may need only water.

Is it okay to clean old or historic headstones?

Older or historic headstones should be cleaned with extreme caution, and in some cases left to professionals or preservation specialists.
