Stone sculptures are timeless works of art that require careful maintenance to preserve their beauty. Cleaning them improperly can lead to irreversible damage, so it's crucial to use gentle, non-invasive methods. Here are the best techniques for safely cleaning stone sculptures:

1. Dry Cleaning First: Always start with the least invasive method. Use a soft-bristled brush or microfiber cloth to remove loose dirt and dust. Avoid abrasive materials that could scratch the surface.

2. Distilled Water Rinse: For light stains, use distilled water (never tap water, which may contain minerals) with a pH-neutral sponge. Gently dab the surface without scrubbing, then dry immediately with a clean cloth.

3. Specialized Stone Cleaners: Choose pH-balanced cleaners designed for stone. Test any product on a small, inconspicuous area first. Avoid acidic or alkaline solutions that can erode the stone.

4. Poultice for Stubborn Stains: For deep-set stains, apply a poultice made of baking soda and distilled water. Cover the paste with plastic wrap and let it sit for 24 hours before gently removing it.

5. Professional Consultation: For valuable or historical pieces, consult a conservator. Improper cleaning can devalue sculptures or destroy delicate patinas.

Preventative care is key—keep sculptures away from direct sunlight, humidity, and pollutants. Regular light dusting is better than intensive cleaning sessions. By following these methods, your stone sculptures will remain pristine for generations.
