Bronze sculptures require distinct maintenance approaches depending on their placement. Indoor bronze pieces benefit from stable environments but need regular dusting with soft microfiber cloths and occasional waxing with museum-grade paste wax to maintain luster. Avoid chemical cleaners that might damage delicate patinas.

Outdoor bronze faces greater challenges from weather, pollution, and biological growth. Monthly inspections for corrosion or green verdigris are essential. Use pH-neutral bronze cleaners and soft brushes for cleaning, followed by protective wax applications every 3-6 months. Pay special attention to drainage holes to prevent water accumulation.

Both environments require gentle handling - never use abrasive materials or high-pressure washing. For valuable pieces, consider professional conservation every 2-3 years. Outdoor sculptures may need more frequent touch-ups due to environmental exposure, while indoor pieces primarily require preventive care against humidity and dust.

The key difference lies in protection focus: outdoor maintenance prioritizes weather resistance, while indoor care emphasizes surface preservation. Always test cleaning products on inconspicuous areas first, and document your maintenance routine for consistent care.
