Bronze sculptures near saltwater are highly susceptible to corrosion due to the harsh marine environment. To preserve their beauty and longevity, several effective methods can be employed.

1. Protective Coatings: Apply wax or lacquer coatings specifically designed for bronze. These create a barrier against salt and moisture. Microcrystalline wax is a popular choice for its durability.

2. Regular Cleaning: Rinse sculptures frequently with fresh water to remove salt deposits. Use a soft brush and mild soap for deeper cleaning, avoiding abrasive materials.

3. Environmental Controls: Position sculptures away from direct exposure to ocean spray. Sheltered locations or indoor displays significantly reduce corrosion risks.

4. Sacrificial Anodes: Install zinc or magnesium anodes near the sculpture. These metals corrode preferentially, protecting the bronze through galvanic action.

5. Professional Maintenance: Schedule annual inspections by conservation experts to address early signs of corrosion and reapply protective treatments.

By combining these strategies, bronze sculptures can withstand saltwater exposure while maintaining their artistic integrity for generations.
