How do polypropylene outdoor chairs handle exposure to tannins from tree leaves?
Polypropylene outdoor chairs are highly resistant to tannins from tree leaves due to their non-porous and chemically inert nature. Unlike natural materials like wood or fabric, polypropylene does not absorb tannins, preventing unsightly stains or discoloration. The plastic's smooth surface also makes it easy to clean—simply wiping with soapy water removes any residue. However, prolonged exposure to wet leaves may cause minor surface dullness over time. To maintain longevity, regularly rinse chairs and avoid letting leaf litter accumulate. For severe cases, a diluted bleach solution can restore brightness without damaging the material. Polypropylene's durability makes it a practical choice for gardens or patios with heavy tree coverage.
