How do cast iron outdoor sculptures handle exposure to ammonia-based cleaning products?
Cast iron outdoor sculptures are durable but require careful maintenance when exposed to ammonia-based cleaning products. Ammonia can accelerate rust formation by stripping protective coatings and reacting with iron. Over time, this leads to pitting, discoloration, and structural weakening. To minimize damage, dilute ammonia solutions heavily and rinse sculptures immediately with water after cleaning. Applying a fresh wax or sealant layer post-cleaning helps restore protection. For long-term preservation, consider pH-neutral alternatives specifically formulated for metal art. Regular inspections and prompt rust treatment will extend your sculpture's lifespan despite occasional ammonia exposure.
