Woven urban outdoor furniture, particularly high-quality synthetic wicker made from polyethylene (PE) or polyvinyl chloride (PVC) resin, exhibits excellent resistance to mold and mildew in humid climates. The primary defense lies in the materials themselves. These synthetic fibers are non-porous, meaning they do not absorb moisture—the essential element for mold and mildew growth. Unlike natural rattan or wood, water beads up and runs off the surface, preventing the damp environment fungi need to thrive.
Furthermore, the aluminum or powder-coated steel frames used in quality sets are also treated for corrosion and moisture resistance. For optimal performance, it is crucial that the furniture is designated as "all-weather" or "UV-resistant." While highly resistant, no outdoor furniture is entirely immune. Mold can sometimes appear on surface dirt or organic debris that accumulates. Regular cleaning with mild soap and water, ensuring proper water drainage through design, and using protective covers during extended wet periods will maintain its pristine condition and maximize its longevity in steamy, humid environments.
