How do polypropylene outdoor chairs resist damage from bird droppings or sap?

Polypropylene outdoor chairs are highly resistant to damage from bird droppings and sap due to their non-porous, chemically inert material. Unlike wood or metal, polypropylene does not absorb liquids, preventing stains and corrosion. The smooth surface allows for easy cleaning, as droppings or sap can be wiped off without leaving residue. Additionally, polypropylene is UV-stabilized, ensuring it won’t degrade or discolor when exposed to sunlight or organic matter. This makes it an ideal choice for durable, low-maintenance outdoor furniture that withstands harsh environmental elements.
