To eliminate musty odors from outdoor furniture cushions, begin by removing all cushion covers if possible. Create a cleaning solution using equal parts white vinegar and water, or mix two tablespoons of baking soda with one cup of water. Scrub the cushions thoroughly with your chosen solution using a soft brush, paying extra attention to stained or particularly smelly areas. For persistent odors, sprinkle baking soda directly onto the cushions and let it sit for several hours before brushing it off.
After cleaning, ensure cushions dry completely in direct sunlight, which naturally kills odor-causing bacteria and mold. Flip cushions periodically to ensure all sides dry thoroughly. For non-removable covers, use a wet vacuum or steam cleaner to extract moisture and odors. To prevent future musty smells, store cushions in a dry, well-ventilated area when not in use, and consider using waterproof storage containers. Regular maintenance, including quick wipes after rain and periodic deep cleaning, will keep your outdoor cushions fresh and extend their lifespan.
For particularly stubborn odors, commercial fabric cleaners designed for outdoor use can be effective. Always test any cleaning solution on a small, inconspicuous area first to ensure it doesn't damage the fabric. With proper care and these cleaning techniques, your outdoor cushions can remain fresh and inviting throughout the entire season.
