Bronze sculptures are prized for their beauty and durability, but over time, oxidation can cause unsightly damage. To restore these artworks, follow these proven methods:

1. Gentle Cleaning: Start by removing loose dirt with a soft brush or microfiber cloth. Avoid abrasive materials that could scratch the surface.

2. Natural Solutions: Mix distilled water with a small amount of mild soap or baking soda to create a gentle cleaning solution. Apply with a soft cloth, then rinse thoroughly.

3. Lemon Juice and Salt: For stubborn oxidation, a paste of lemon juice and salt can be applied sparingly. Rinse immediately to prevent over-etching.

4. Commercial Cleaners: Use specialized bronze cleaners for deeper oxidation. Always test on a small, hidden area first.

5. Wax Coating: After cleaning, apply a thin layer of museum-grade wax to protect the surface and slow future oxidation.

6. Professional Restoration: For severe damage, consult a professional conservator to ensure the sculpture’s integrity is preserved.

By following these steps, you can effectively repair oxidation damage and maintain the sculpture’s original luster for years to come.
