Algae growth on outdoor furniture in constantly shaded urban areas is a common nuisance, fueled by moisture and lack of sunlight. The best way to clean it involves a safe, multi-step process. First, remove loose debris with a soft brush. For a highly effective and eco-friendly DIY solution, mix equal parts white vinegar and water in a spray bottle. For tougher growth, use a paste of baking soda and water. Apply your chosen cleaner, let it sit for 15-20 minutes to penetrate the algae, then scrub vigorously with a stiff-bristled brush (non-metallic for delicate surfaces). Rinse thoroughly with a garden hose or a low-pressure setting on a pressure washer to avoid damage. For prevention, ensure airflow by occasionally moving furniture, use breathable, algae-resistant covers, and apply a commercial waterproof sealant designed for outdoor fabrics and materials. Regular, light cleanings are far easier than removing established growth. Always test any cleaner on a small, inconspicuous area first to ensure it doesn't damage the finish.
