Tombstones and headstones are not only places where we remember our loved ones, but also an important part of our culture and history. Regular and professional stone care helps preserve its appearance and significantly extends its lifespan. In this article, you will find all the practical information and step-by-step procedures to properly clean, protect, and maintain a headstone without risking damage.
Tombstone Materials
Before starting any work, it is crucial to accurately identify the material the headstone is made of. Different types of stone require distinct cleaning approaches and chemical products. As many as nine out of ten people believe they need to care for marble, when in reality it is most often granite or terrazzo. We addressed this topic in detail in our article Granite or Marble? A Few Tips on How to Correctly Identify Stone.
Step by Step: How to Clean a Tombstone
1. Evaluating the Condition
Before you begin cleaning, inspect the stone surface thoroughly. If it is visibly damaged, cracked, or flaking, it may be safer to consult a professional to prevent further breakdown.
Accurate diagnosis of the contamination is key to success. Determine whether you need a cleaner for organic stains (leaves, moss, tree resin), a cleaner for inorganic stains (candle wax, grease, wreath paint), or a specialized rust remover.
2. Basic Cleaning Equipment
To get started, prepare:
- A soft brush, hand cleaning pads, or fine steel wool.
- A bucket or watering can of clean water for rinsing, plus a bucket for diluting the stone cleaner.
- A specialized stone cleaning agent suitable for your stone type (never use acidic cleaners on marble or limestone, as they will etch and dull the polish).
- Protective rubber gloves.

3. Removing Surface Dirt
Start by sweeping off dust, loose moss, and lichens using water and a soft brush. Avoid using hard wire brushes or harsh metal tools that could permanently scratch polished surfaces.
4. Using Professional Stone Chemicals & Deep Cleaning
A common mistake is using regular household dish soaps or detergents. Specialized stone cleaners are formulated to react and rinse away completely upon washing. Household detergents, on the other hand, remain trapped in the stone's pores and reactivate every time it rains, accelerating erosion and material degradation over time.
If the stone is heavily soiled, apply the cleaner, let it act for a few minutes, and gently scrub with a brush or cleaning pad. Avoid acidic products on soft stones. Repeat the process if necessary.
5. Thorough Rinsing
After cleaning, rinse the headstone thoroughly with plenty of clean water. The surface must be completely dry and clean before applying any protective impregnator.
Quick Overview of Top Cleaners:
- Rust Remover (Mangia Ruggine) – extracts deep rust stains caused by wire frames and floral wreaths.
- Organic Stain Cleaner (BERT 27) – effectively removes moss, lichens, and stubborn leaf stains.
- Degreaser & Cleaner (Ultra Stripper) – removes inorganic grime, candle wax residues, and old wax coatings.

Tombstone Protection: Impregnation & Sealing
Once cleaned and thoroughly dried, we recommend treating the stone with a high-quality impregnating sealer. The protective coat seals pores, repels water and oils, and prevents new dirt or moss from taking root.
How Does Stone Impregnation Work?
Quality stone impregnators are vapor-permeable. This means they prevent external water and liquids from penetrating into the stone while allowing internal moisture to "breathe" out naturally.
PLEASE NOTE: Impregnation itself does not create a high gloss – it is not a polish or varnish. Its main job is protection. However, depending on the product chosen, it can either maintain a natural look or enhance the original color of the stone.
Important Precautions When Applying Stone Chemicals
Always read the product instructions carefully before application. If an incorrect product is applied or used improperly, there is often no easy "undo" button.
Critical Warning: If a porous material absorbs an unsuitable impregnator that cures inside, it cannot be dissolved out. This can leave permanent stains and visual flaws on the stone.
We supply premium stonemasonry chemical solutions from the Italian manufacturer Bellinzoni. Our team undergoes regular technical training directly from the manufacturer, allowing us to recommend exact procedures for your specific material. Unfortunately, clients often contact us only after their stone has been damaged by generic hardware store products where proper technical guidance was missing.
Choosing the Right Impregnator by Material
- Terrazzo and Sandstone (Highly Porous): Require consolidating and strengthening sealers. We recommend impregnators with a strengthening effect (Strong 2000) or with color enhancement (Grezzo).
- Marble and Travertine: Require delicate yet effective protection. Ideal choices include nanotechnology impregnators (Idea Gold) or darkening sealers for dark shades (Idea Black).
- Polished Granite: Offers a wide variety of finishes – the most popular being the wet look effect (Idea XC) or black stone color darkener (Idea Dark).
Best Practices for Impregnator Application
- Cleanliness: The stone must be 100% clean. Impregnation will seal in any existing stains or dirt, making them impossible to remove later.
- Dryness: The surface must be completely dry. Moisture inside the pores will block the impregnator and cause patchy discoloration.
- Temperature: Never apply on sun-heated stone! High temperatures cause solvents to evaporate too quickly, leaving a weak film on the surface with short lifespan.
- Coating: Apply 2 to 3 thin coats (depending on absorbency). Allow at least 3 hours of drying time between coats.
Routine Maintenance
Deep cleaning and impregnation only need to be done once every few years. For routine touch-ups throughout the year, we recommend a practical Lava Lucida cleaning & polishing spray, which quickly refreshes the surface and removes dust.
Restoring Tombstone Lettering
If you followed the cleaning and sealing steps above, your headstone is now thoroughly clean and protected. However, faded or peeling lettering can still spoil the overall appearance. Inscriptions naturally lose their sharpness and luster over time.
While you can hire a professional stonemason, many lettering touch-ups can be done yourself. You can re-gild the letters using real gold leaf or repaint them using specialized durable tombstone paint.
