The best way to clean mildew off woven urban outdoor furniture involves a systematic approach using safe, effective solutions. First, move the furniture to a shaded, well-ventilated area. Brush off loose dirt and debris with a soft-bristled brush. Create a cleaning solution by mixing one part distilled white vinegar with one part warm water. For tougher mildew, a solution of one tablespoon of mild, oxygen-based bleach (like sodium percarbonate) per cup of warm water is highly effective and color-safe. Always test any solution on a small, inconspicuous area first.
Apply the chosen solution using a spray bottle or a soft sponge, thoroughly saturating the mildewed areas. Allow it to sit for 10-15 minutes to penetrate and kill the mold spores. Gently scrub the weave with a soft-bristled brush, following the pattern of the weave to avoid damage. Rinse the furniture completely with a hose or a bucket of clean water to remove all cleaning residue. It is crucial to let the furniture dry fully in the sun before use or storage, as moisture is the primary cause of mildew. To prevent future growth, regularly dust your furniture, use protective covers when not in use for extended periods, and store it in a dry place during harsh weather. This method effectively removes mildew without damaging the delicate fibers of woven urban furniture.
