Why are cast iron outdoor chairs prone to leaving rust marks on pavements?
Cast iron outdoor chairs are prone to leaving rust marks on pavements due to the natural oxidation process of iron. When exposed to moisture, such as rain or humidity, the iron in the chairs reacts with oxygen, forming iron oxide (rust). Over time, this rust can transfer onto pavements, especially when the chairs are moved or dragged. The porous nature of many paving materials, like concrete or stone, allows the rust to seep in, creating stubborn stains. To minimize this issue, consider using protective coatings on the chairs, placing them on non-porous surfaces, or opting for rust-resistant outdoor furniture alternatives. Regular maintenance, such as drying the chairs after rain, can also help reduce rust formation.
