Bronze sculptures are timeless works of art, but surface etching can mar their beauty over time. To prevent this, start by applying a high-quality protective wax or lacquer, which creates a barrier against moisture and pollutants. Regular cleaning with a soft cloth and mild soap helps remove corrosive residues without damaging the surface. Controlling the environment is crucial—keep sculptures away from high humidity, direct sunlight, and acidic pollutants. For outdoor pieces, consider microcrystalline wax coatings, which offer long-lasting protection. Additionally, avoid touching bronze with bare hands, as oils and acids from skin can accelerate etching. By combining these methods, you can preserve the integrity and appearance of bronze sculptures for generations.
