Even though this is an outdoor fabric, we do recommend bringing cushions inside when not in use to avoid excessive wetness or sunlight. Brush off loose dirt and tend to spills or stains with a mixture of cool water and mild, natural soap (no detergents). Use a soft bristle brush to clean and be sure to rinse thoroughly before air drying. Repeat as needed. For more stubborn stains, unzip the pillow, remove inner cushioning, and wash fabric on a gentle cycle of your washing machine, using cold water for the wash and rinse cycles. We recommend an all-natural soap, no detergents. Hang to dry. Do not put in the dryer.
