What happens to uncoated cast iron outdoor bar stools in tropical humidity?

Uncoated cast iron outdoor bar stools are highly susceptible to damage in tropical humidity due to prolonged exposure to moisture. The high moisture content in the air accelerates oxidation, leading to rapid rust formation and corrosion. Over time, this weakens the metal, causing pitting, flaking, and structural instability. Without protective coatings like paint or sealants, the stools may develop unsightly reddish-brown rust stains and become unsafe for use. To prolong their lifespan, regular cleaning, drying, and applying rust-resistant treatments are essential. In extreme cases, uncoated cast iron stools may require replacement if corrosion compromises their integrity. Proper maintenance is key to preserving their durability in humid climates.
