Mildew on outdoor furniture is a common but fixable problem. The best cleaning method depends on your furniture's material. For general surfaces like plastic, resin, or metal, create a cleaning solution of one part white vinegar to one part warm water. Apply it, let it sit for 10-15 minutes, then scrub with a soft brush and rinse thoroughly. For stubborn mildew on these materials, a solution of ¾ cup bleach mixed with one gallon of water can be effective—always test in an inconspicuous area first and rinse well.
For outdoor cushions with mildew, check the care label. If machine washable, use the hottest water safe for the fabric with detergent and add ½ cup of white vinegar or bleach (if suitable for the fabric). For non-removable covers or delicate fabrics, mix a mild detergent with warm water, scrub gently with a soft brush, and rinse completely. A paste of baking soda and water can also help lift stains.
Teak furniture requires gentler care to preserve its oils. Use a specialized teak cleaner or a mild soap and water solution. Avoid harsh chemicals like bleach or vinegar on teak.
After cleaning, the most crucial step is to let the furniture dry completely in the sun before using or covering it. To prevent future mildew growth, store cushions indoors when not in use, use breathable, waterproof furniture covers, and clean your furniture periodically throughout the season. Regular maintenance is the key to keeping your outdoor space looking fresh and mold-free.
