Mold on outdoor cushions is a common problem caused by moisture and lack of airflow. To stop it, start by choosing cushions made of quick-drying, mold-resistant fabrics like solution-dyed acrylic or polyester. Always use waterproof, breathable covers when not in use, especially overnight or during rain. Ensure cushions are completely dry before storing them. If they get wet, prop them up vertically to allow air circulation on all sides.
For existing mold, create a cleaning solution of one cup bleach, one-third cup mild soap, and one gallon of warm water. Test on a small area first. Scrub the mold gently with a soft brush, then rinse thoroughly with a hose. Let the cushions dry completely in direct sunlight, which helps kill mold spores.
For regular maintenance, vacuum cushions weekly and clean them with a mild soap solution monthly during the season. For long-term storage, keep cushions in a cool, dry place like a garage or shed, ideally on a shelf and not directly on concrete. Consider using moisture-absorbing products like silica gel packets in the storage area. Following these steps will significantly extend the life and appearance of your outdoor cushions.
