How to Remove Stains from Gris Zéphyr Granite on Headstones and Cemetery Monuments

Gris Zéphyr granite is an elegant, durable material widely used for cemetery monuments and headstones. Despite its robustness, it can be exposed to weather, pollution, moss, and residues from flowers or candles, leaving unsightly stains. Fortunately, with the right methods and products, it is possible to restore its original shine.

1. Identify the Source of the Stains

Before cleaning, it’s important to determine the type of stain:

• Moss and lichens: green or dark spots caused by moisture.

• Candle wax: greasy stains that are difficult to remove.

• Wilted flowers: organic deposits leaving brown marks.

• Pollution and dust: grayish film that dulls the stone.

2. Effective Cleaning Methods

• Clean water and black soap: for general dirt, gently scrub with a soft sponge or non-metal brush.

• Baking soda: effective on stubborn stains (mix with a little water to form a paste and apply locally).

• Special granite products: use professional cleaners like Lithofin MN Outdoor Cleaner, Starwax Natural Stone Cleaner, or other products recommended by stonemasons. These solutions are designed to remove moss, black stains, and deposits without damaging the polished surface of Gris Zéphyr granite.

⚠️ Avoid bleach, acidic, or overly abrasive products as they can permanently damage the polished granite.

3. Removing Specific Stains

• Candle wax: gently scrape the surface with a plastic spatula, then clean with black soap.

• Moss and lichens: apply a stone-safe anti-moss product, then rinse thoroughly.

• Grease stains: apply a paste of baking soda or French “terre de Sommières,” let it sit for a few hours, then rinse.

4. Preventing New Stains

Regular maintenance helps keep Gris Zéphyr granite looking its best:

• Clean the grave at least twice a year (spring and autumn).

• Remove wilted flowers and standing water from vases promptly.

• Apply a suitable stone-protective treatment if needed to repel moisture and dirt.
