Outdoor cushions can be simple to clean and each will have its own care instructions that you should follow. That being said, with most outdoor cushions if you are looking for a time-efficient option, wipe down your outdoor cushion with a wet cloth to remove dirt and debris. However, for a deeper clean, remove the outdoor cushion cover and place it in a cool machine wash with a gentle cycle. Then, hang out to dry. Do not soak or bleach. Do not tumble dry. Cool iron on reverse.
