Algae growth on outdoor furniture in shaded, urban areas is a common nuisance due to limited sunlight and moisture retention. The best way to clean it involves a safe, multi-step process. First, move the furniture to an open area if possible. For a gentle, eco-friendly clean, create a solution of equal parts white vinegar and water or a mixture of 1 gallon warm water with 1/2 cup baking soda. Apply generously, let it sit for 15-20 minutes to break down the algae, then scrub vigorously with a stiff-bristled brush (non-metallic for delicate surfaces). Rinse thoroughly with a garden hose. For stubborn growth on durable materials like metal or hard plastic, a low-pressure power washer setting can be effective, but hold the nozzle at least 12 inches away to avoid damage. Always test any cleaner on a small, hidden area first. To prevent rapid regrowth, ensure furniture dries completely after rain, use breathable covers, and consider applying a commercial outdoor furniture protectant. Regular light cleaning is more effective than tackling severe buildup.
