Bronze sculptures are prized for their beauty and durability, but they are vulnerable to electrolytic corrosion, which can degrade their appearance and structural integrity over time. To preserve these artworks, several effective methods can be employed.

1. Apply Protective Coatings: Wax or lacquer coatings create a barrier against moisture and pollutants. Microcrystalline wax is particularly effective for outdoor sculptures, while acrylic lacquers offer long-term protection for indoor pieces.

2. Control Environmental Exposure: Limit exposure to saltwater, acidic rain, and high humidity. Indoor sculptures should be kept in stable environments with controlled temperature and humidity levels.

3. Regular Cleaning and Maintenance: Gently clean bronze sculptures with distilled water and a soft brush to remove dirt and pollutants. Avoid abrasive materials that could damage the patina.

4. Use Sacrificial Anodes: For sculptures in harsh environments, attaching zinc or magnesium anodes can divert corrosive reactions away from the bronze.

5. Monitor and Repair Patina: The natural patina on bronze acts as a protective layer. Regularly inspect it and consult a conservator for repairs if cracks or discoloration appear.

By combining these methods, you can significantly reduce the risk of electrolytic corrosion and ensure your bronze sculptures remain stunning for generations.
