Stone sculptures, whether antique or modern, require careful cleaning to preserve their beauty and integrity. Harsh methods can erode surfaces or discolor the material, so gentle techniques are essential. Here are the best practices for cleaning stone sculptures safely:

1. Dust Regularly: Use a soft-bristled brush or microfiber cloth to remove loose dirt and dust. Avoid abrasive materials that could scratch the surface.

2. Use Distilled Water: If water is needed, opt for distilled water to prevent mineral deposits. Dampen a cloth lightly—never soak the stone, as excess moisture can cause damage.

3. Mild Soap Solution: For stubborn grime, mix a few drops of pH-neutral soap with distilled water. Gently wipe the sculpture, then rinse with a damp cloth and dry immediately.

4. Avoid Chemicals: Harsh cleaners like bleach or acids can corrode stone. For biological growth (e.g., algae), consult a conservator for specialized treatments.

5. Professional Help: Valuable or fragile sculptures should be handled by experts to prevent irreversible damage.

By following these methods, you can maintain your stone sculptures' longevity while keeping their original charm intact.
