Mildew stains on wicker outdoor furniture are a common problem, but they can be effectively removed with some simple cleaning solutions. First, take the furniture to a well-ventilated area. Use a soft brush or vacuum with a brush attachment to remove loose dirt and debris. For the cleaning solution, a mixture of equal parts white vinegar and water is highly effective against mildew. Alternatively, you can use a mild solution of dish soap and warm water. For tougher stains, make a paste using baking soda and water.
Apply your chosen cleaner with a soft-bristled brush, scrubbing gently along the weave to avoid damaging the wicker. Let the vinegar solution sit for about 15 minutes to penetrate the mildew. After scrubbing, rinse the furniture thoroughly with a garden hose or a damp cloth, ensuring no cleaning residue remains. It is crucial to let the wicker dry completely in the sun before using or storing it, as moisture is the primary cause of mildew growth. To prevent future mildew, regularly dust your wicker furniture and store it in a dry place or use protective covers during wet seasons. With proper care, your wicker furniture can stay clean and last for many seasons.
