How to Get Rid of Mildew on Outdoor Cushions: 1 Minute to a Mold-Free Outdoor Space

Mildew on outdoor cushions is a common problem, especially in humid or rainy climates. The musty odor and unsightly stains can diminish the look and comfort of your outdoor spaces. To effectively remove mildew from your cushions, start by brushing off any loose spores using a soft-bristle brush outdoors—this prevents spreading spores inside your home. Next, mix a solution of one part mild dish soap, one part white vinegar, and four parts warm water. Apply the mixture generously to the affected areas using a sponge or cloth, gently scrubbing to lift the mildew. Let it sit for at least 15 minutes, then rinse thoroughly with a hose. For stubborn mildew, sprinkle baking soda directly on the spots, scrub, and rinse. Finally, ensure the cushions dry completely in direct sunlight, which naturally helps kill lingering spores.

As a designer, I always consider both function and aesthetics. If mildew is a recurring issue, consider the design and quality of your outdoor soft furnishings: opt for cushions with removable, washable covers, or materials engineered for durability outdoors. This not only extends the life of your furniture, but also gives you greater freedom to style your patio with bold colors and patterns, knowing upkeep is simple. When planning your outdoor living areas, I often use a room design tool to visualize furniture placement for optimal airflow and ease of maintenance, helping prevent issues like mildew from recurring by ensuring better sunlight exposure.

Tips 1:

Regularly rotate and flip cushions, especially after rain, to aid thorough drying and discourage mildew growth.
