Porous stone sculptures are highly susceptible to staining due to their absorbent nature. To preserve their beauty, follow these proven methods:

1. Apply a High-Quality Sealant: Use a penetrating stone sealant designed for porous materials. Reapply every 1-2 years to maintain protection.

2. Clean Regularly with pH-Neutral Solutions: Avoid acidic or abrasive cleaners. Instead, use mild soap and water to gently remove dirt before it penetrates.

3. Address Spills Immediately: Blot liquids (especially oils, wine, or coffee) with a clean cloth—never wipe, as this spreads the stain.

4. Avoid Direct Sunlight and Moisture: Prolonged exposure can weaken the stone’s surface, making it more prone to staining.

5. Use Protective Barriers: Place sculptures on non-porous stands or coasters to prevent ground moisture absorption.

For deep stains, consult a professional stone restorer. Consistent care ensures your porous stone sculptures remain pristine for generations.
