Bronze sculptures are prized for their beauty and durability, but improper cleaning can cause irreversible damage. Over-cleaning or using harsh chemicals strips away the protective patina—a natural oxidation layer that develops over time. This patina not only enhances the sculpture's aesthetic but also shields the metal from further corrosion.

Aggressive cleaning methods, such as abrasive scrubbing or acidic solutions, can etch the surface, leaving scratches or uneven textures. Chemicals like bleach or ammonia accelerate tarnishing and may react with the bronze, causing discoloration or pitting. Even mild cleaners, if overused, can weaken the sculpture's structural integrity by removing too much material.

To preserve bronze artworks, opt for gentle techniques like dusting with soft brushes or using pH-neutral soap sparingly. Professional conservators recommend minimal intervention to maintain the sculpture's historical and artistic value. Always test cleaning products on inconspicuous areas first and consult experts for valuable pieces.

By understanding these risks, collectors and caretakers can ensure bronze sculptures retain their legacy for generations.
