Preserving the Past: How to Properly Clean Historical Headstones

Tips and Tricks – Cleaning headstones is an important part of preserving the beauty and integrity of these historical markers. Whether you are a caretaker of a cemetery or have a loved one buried there, knowing how to properly clean headstones is crucial. 

In this article, we will guide you through the process of cleaning headstones effectively and safely.

1. Understanding the Headstone Material

Before you start cleaning a headstone, it’s essential to understand the material it is made of. Headstones can be made from various materials such as granite, marble, limestone, or bronze. Different materials require different cleaning methods and products to avoid damage.

1.1 Granite Headstones

Granite headstones are durable and commonly used. To clean a granite headstone, use a soft-bristle brush and a non-ionic detergent mixed with water. Avoid using acidic or abrasive cleaners as they can cause damage.

1.2 Marble Headstones

Marble headstones are more delicate and prone to erosion. Clean marble headstones with a soft brush and a mild, non-ionic detergent mixed with water. Avoid using acidic or abrasive cleaners, as they can etch the surface of the marble.

2. Gathering the Cleaning Supplies

To clean headstones effectively, gather the necessary cleaning supplies. You will need:

  • A soft-bristle brush
  • A non-ionic detergent
  • Distilled water
  • A plastic scraper
  • Cotton swabs
  • A bucket
  • Gloves
  • Protective goggles
  • Soft cloths or sponges

3. Preparing the Headstone

Before applying any cleaning solution, gently remove loose debris and dirt from the headstone using a soft brush or cloth. This step helps prevent scratching during the cleaning process.

4. Cleaning the Headstone

Dilute the non-ionic detergent in a bucket of distilled water according to the manufacturer’s instructions. Wet the headstone with clean water, and then apply the detergent solution using a soft brush or sponge. Scrub gently in a circular motion, paying attention to stained or soiled areas.

For stubborn stains, use a plastic scraper or a cotton swab soaked in the cleaning solution. Be cautious not to scratch or damage the surface of the headstone. Rinse the headstone thoroughly with clean water, ensuring all traces of the detergent are removed.

5. Drying and Protecting the Headstone

After cleaning, use soft cloths or sponges to pat the headstone dry gently. Avoid rubbing, as it can cause friction and potential damage. Let the headstone air dry completely before applying any protective sealants or coatings.

6. Applying Sealants or Coatings (If Necessary)

Applying a sealant or coating to the headstone can provide extra protection against weathering and staining. However, not all headstones require sealants, so it’s crucial to consult with a professional or refer to the manufacturer’s guidelines before applying any products. If you decide to apply a sealant or coating, choose one specifically designed for the type of headstone material you are working with. Follow the instructions carefully and apply it evenly using a soft brush or cloth. Allow the sealant to dry completely before touching or exposing it to moisture.

7. Regular Maintenance

To keep headstones looking their best, regular maintenance is essential. Here are some tips for ongoing care:

  • Regularly remove debris and dirt using a soft brush or cloth.
  • Wash the headstone with water at least once a year to remove surface buildup.
  • Avoid using harsh chemicals, acidic cleaners, or abrasive tools.
  • Monitor for any signs of damage or deterioration and take appropriate action.

8. Seeking Professional Assistance

If you are unsure about cleaning or maintaining a headstone, it’s always best to seek professional assistance. There are experts who specialize in headstone restoration and preservation, and they can provide valuable guidance and services to ensure the longevity of the memorial.


Cleaning headstones is a task that requires careful attention and knowledge of the appropriate methods and products. By understanding the material, gathering the necessary supplies, and following proper cleaning techniques, you can effectively clean and preserve headstones for years to come. Remember to always prioritize the gentle treatment of headstones to avoid causing any damage.
