Before storing your outdoor cushions for the winter, or between uses, ensure they’re clean and entirely dry. Depending on the material, you may need to simply wipe the cushions down with a rag and some dish soap, or you may be able to spray with vinegar and water or bleach solution to remove any mildew or stains. Never put cushions away while they’re damp, or they will develop mold and mildew. Once dry, you can put them in a waterproof deck storage box or outdoor storage shed. You may want to include mothballs or other pest repellents to prevent bugs from nesting inside the safe haven of your outdoor storage container and ruining your cushions. Moths, ants, stink bugs, and many other types of nuisance bugs love hiding out in cushions—and some can eat right through just about any kind of material.
