How to Clean a Granite Headstone: Tips and Techniques for Preserving Memories

Understanding Granite Headstones

A granite headstone is a common type of tombstone or grave marker found in cemeteries. Granite is a natural stone that is tough, durable, and easy to maintain, making it an ideal material for headstones. However, granite headstones can accumulate dirt, grime, and stains over time, especially in outdoor environments. Therefore, cleaning and maintaining a granite headstone is essential to preserve its aesthetic appeal and honor the memories of the deceased.

Before you start cleaning a granite headstone, it’s crucial to check the state of the headstone. If there is significant damage, such as cracks, chips, or discoloration, do not try to clean the stone yourself. Instead, consult a professional stone restorer or a cemetery representative for advice. Attempting to clean damaged granite headstones could worsen the damage or cause irreversible harm.

If the granite headstone is in good condition, then it’s safe to clean it regularly to keep it looking beautiful. The following are some tips on how to clean a granite headstone:

Steps for cleaning granite headstones

1. Assess the weather conditions

Before starting, ensure that the weather is appropriate for cleaning the granite headstone. Avoid cleaning on a hot, sunny day or a windy day. A cloudy or overcast day is best as the cleaning solution will have enough time to work and will not dry out too quickly.

2. Gather the necessary materials

Gather the required items for cleaning the granite headstone. The essentials include a bucket of water, a soft-bristled brush, a non-ionic detergent, a plastic scraper, and a microfiber cloth. Avoid using harsh chemicals or commercial cleaners that contain acids, alkalis, or bleach as these can cause discoloration or damage the granite surface.

3. Pre-clean the granite headstone

Using a plastic scraper or a brush, remove any debris or loose dirt from the surface of the granite headstone. Avoid using metal tools that could scratch or damage the granite surface.

4. Prepare the cleaning solution

Prepare the cleaning solution by mixing a small amount of non-ionic detergent with warm water in a bucket. Non-ionic detergents are mild, water-soluble cleaning agents that are suitable for use on granite headstones. Avoid using solutions containing acids, alkalis, or bleach as these can cause discoloration or damage to the granite surface.

5. Apply the cleaning solution

Dip the soft-bristled brush into the cleaning solution and apply it gently to the surface of the granite headstone. Scrub gently in a circular motion, ensuring that the entire surface is covered. Avoid using too much pressure or scrubbing too hard as this could cause scratches and damage to the granite surface.

6. Rinse the granite headstone

Rinse the granite headstone thoroughly with clean water, using a bucket or a garden hose. Ensure that all soap residue is removed from the surface of the headstone. Repeat if necessary.

7. Dry the granite headstone

Wipe the surface of the granite headstone with a microfiber cloth and allow it to air dry. Avoid using abrasive materials such as paper towels or sponges that could scratch or damage the surface.


Cleaning a granite headstone requires careful consideration of the type of material and the appropriate cleaning techniques. Using non-ionic detergents, soft-bristled brushes, and plastic scrapers can ensure that the granite headstone is cleaned safely and effectively. Regular cleaning and maintenance of the granite headstone can help preserve its beauty and honor the memories of the deceased.

Gather Materials

If you plan to clean a granite headstone, the first step is to gather all the necessary materials. Before you get started, be sure to wear gloves to protect your hands and to avoid leaving fingerprints or smudges on the monument. Here are the items you’ll need:

  • A soft-bristled brush
  • Clean water
  • A gentle granite cleaner
  • A bucket or spray bottle
  • Protective gloves

When selecting a granite cleaner, it’s important to choose one that is non-acidic, non-abrasive, and formulated specifically for use on granite. Avoid using harsh chemicals such as bleach or ammonia, as they can damage the surface of the stone.

Once you have gathered all of your materials, you’re ready to begin cleaning your granite headstone.

Prepare the Headstone

Before you start cleaning your granite headstone, it’s essential to prepare it. Firstly, remove any loose debris or dirt from the surface of the headstone. Use a soft-bristled brush to avoid any scratches or damage to the granite. If there’s an excessive amount of dirt, use water to rinse it off before brushing.

It’s also crucial to identify any signs of damage or staining on the granite headstone. If you notice any chips, cracks, or discoloration, it’s best to take note of it before starting the cleaning process. These are issues that you may need to address later on to ensure that your headstone remains in good condition for as long as possible.

Once the headstone is free of any loose debris, you can move on to the next step.

Clean the Granite Headstone

When it comes to cleaning a granite headstone, it’s important to use the right products and techniques to avoid damaging the surface. Here are some tips to ensure your loved one’s headstone stays clean and well-maintained:

1. Start with a Gentle Wash

Begin by giving the headstone a gentle wash with soap and water. Use a soft-bristled brush or sponge and avoid any harsh cleaners or abrasives. Be sure to rinse thoroughly to remove any soap residue.

2. Mix a Granite-Safe Cleaning Solution

For tougher stains or buildup, you can create a granite-safe cleaning solution. Mix equal parts water and rubbing alcohol in a spray bottle, and add a few drops of dish soap. Shake well and spray the solution onto the headstone, letting it sit for a few minutes before wiping clean with a soft cloth or sponge.

3. Avoid Harsh Scrubbing

When using a soft-bristled brush to scrub the headstone, be sure to proceed with gentle and controlled strokes. Avoid using excessive pressure, as this could end up scratching or chipping the surface. Use back-and-forth strokes and concentrate on the areas that need the most attention.

4. Remove Tough Stains Carefully

For those tough stains that just won’t budge, it’s crucial to not resort to harsh measures. Avoid using any acidic or abrasive cleaners, as these could damage the granite. Instead, try using a mixture of baking soda and water and apply it to the stain. Allow it to sit for a few hours before gently scrubbing away with a soft-bristled brush.

Alternatively, you can create a poultice by mixing flour and hydrogen peroxide into a thick paste. Apply the paste to the stain and cover it with plastic wrap to keep it moist. After 24-48 hours, remove the poultice and gently clean the area with water.


By following these tips, you can effectively clean your loved one’s granite headstone without causing any harm. Always use gentle products and techniques, and if you’re unsure about a cleaner or method, it’s best to consult a professional. Keeping the headstone clean and maintained is a great way to honor your loved one and ensure their memory lives on for generations to come.

How To Clean Granite Headstone: Final Considerations

When it comes to cleaning granite headstones, it is important to take the necessary precautions to ensure that the material is not damaged. After you are finished cleaning the granite headstone, it is important to rinse it thoroughly with clean water. This is because any cleaning residue left on the headstone could attract dirt and debris, which could lead to discoloration over time.

Another important thing to keep in mind is to avoid using any harsh chemicals or abrasive tools on the granite headstone. This is because granite is a porous material, and any chemicals or abrasive tools could cause damage to the surface of the headstone, leading to cracks, chips and other types of damage.

It is also important to avoid using any acidic cleaning agents, such as vinegar, lemon juice or bleach, as these can cause the granite to discolor and become damaged over time. Instead, opt for a pH-neutral or mild detergent solution, which will be gentle on the headstone while still effectively cleaning it.

If you are unsure about which cleaning solution to use, remember that the simplest solution is often the best. Warm water and a soft-bristled brush are often all that is needed to clean a granite headstone effectively, without causing any damage to the material.

In addition to cleaning the granite headstone, it is also important to take care when it comes to the surrounding area. Avoid placing any objects on top of the headstone, especially heavy or sharp objects that could cause damage.

To help protect the granite headstone from the elements, consider applying a sealant or protective coating. However, always check with the cemetery rules and regulations before applying any product to the headstone, as some cemeteries may have restrictions on what can be applied to the headstone.

In conclusion, cleaning a granite headstone requires a gentle touch and some attention to detail. By taking the necessary precautions and using the right cleaning agents, it is possible to effectively clean a granite headstone without causing any damage or discoloration. With a little care and attention, your loved one’s granite headstone can remain a beautiful and lasting tribute for generations to come.
