Polished metal sculptures are prized for their luster and beauty, but oxidation and tarnish can quickly diminish their appeal. To preserve these artworks, follow these effective methods:

1. Apply Protective Coatings: Use clear lacquer or wax coatings specifically designed for metals. These barriers shield the surface from moisture and air, the primary causes of oxidation.

2. Regular Cleaning: Gently clean sculptures with a soft cloth and mild soap to remove dirt and oils. Avoid abrasive materials that can scratch the surface.

3. Control Humidity: Store or display sculptures in low-humidity environments. Silica gel packs or dehumidifiers can help reduce moisture levels.

4. Use Anti-Tarnish Strips: Place these strips near metal sculptures to absorb corrosive gases, slowing tarnish formation.

5. Avoid Direct Handling: Oils from skin accelerate tarnish. Wear gloves when handling polished metal pieces.

By combining these techniques, you can maintain the brilliance of polished metal sculptures for years to come.
