How do cast iron outdoor sculptures handle exposure to fertilizers or agricultural chemicals?
Cast iron outdoor sculptures are durable but can be affected by prolonged exposure to fertilizers or agricultural chemicals. These substances often contain salts and acids that accelerate rust formation by breaking down the protective patina or paint layer. To minimize damage, regularly clean sculptures with water to remove chemical residues and apply a fresh coat of sealant or wax. Placing sculptures away from direct fertilizer application areas also helps. For severe rust, sanding and repainting may be necessary. Proper maintenance ensures longevity despite chemical exposure.
