Patinated bronze sculptures are prized for their timeless beauty, but surface stains can detract from their aesthetic appeal. To restore these artworks, follow these expert-approved methods:

1. Gentle Cleaning with Distilled Water: Start by wiping the stained area with a soft cloth dampened with distilled water. Avoid tap water, as minerals may worsen discoloration.

2. Mild Soap Solution: For stubborn stains, mix a pH-neutral soap with distilled water. Use a soft-bristle brush to gently scrub, then rinse and dry immediately.

3. Baking Soda Paste: Create a paste with baking soda and water for localized stains. Apply sparingly, leave for a few minutes, then wipe clean.

4. Professional Wax Coating: After cleaning, apply a museum-grade wax to protect the patina and prevent future staining.

5. Consult a Conservator: For severe stains or valuable pieces, seek professional art restoration services to avoid irreversible damage.

Always test cleaning methods on an inconspicuous area first. Regular maintenance and proper display conditions can minimize future staining.
