How do cast iron outdoor sculptures handle exposure to organic acids from decaying leaves?
Cast iron outdoor sculptures are known for their durability, but exposure to organic acids from decaying leaves can pose challenges. Over time, tannins and other acids released by decomposing foliage may accelerate rust formation on untreated or poorly maintained surfaces. However, high-quality cast iron sculptures are typically coated with protective sealants or patinas that resist such corrosion. Regular maintenance, including seasonal cleaning and waxing, further shields the metal. In damp environments, prompt leaf removal is recommended to minimize prolonged acid contact. While some weathering adds character, proactive care ensures these artworks withstand organic decay while maintaining structural integrity and aesthetic appeal.
