Bronze sculptures are timeless works of art, but over time, they can develop a sticky or gummy surface due to environmental factors and improper care. To maintain their beauty and integrity, follow these effective prevention methods:

1. Regular Cleaning: Use a soft, lint-free cloth to gently wipe the sculpture weekly. Avoid harsh chemicals—opt for mild soap and distilled water for deeper cleaning.

2. Control Humidity: High moisture accelerates oxidation and stickiness. Display sculptures in a climate-controlled environment (ideally 40-50% humidity) or use silica gel packs nearby.

3. Apply Protective Wax: A thin layer of microcrystalline wax forms a barrier against pollutants. Reapply every 6-12 months, buffing gently for a natural sheen.

4. Avoid Direct Handling: Oils from skin can degrade the bronze. Wear gloves when moving or cleaning sculptures.

5. Monitor Patina: If the sculpture has a patina, consult a conservator before cleaning. Unauthorized treatments may damage the finish.

For stubborn stickiness, a professional conservator can safely remove residue without harming the metal. By combining these steps, your bronze sculptures will remain pristine for generations.
