Using these pillow covers is easy. Just unzip the cover and insert your pillow or the included fill. You can place them on your indoor sofa, armchair, or take them outside to spruce up your patio furniture. When it comes to cleaning, simply follow the care instructions on the label. Usually, you can machine - wash them in cold water on a gentle cycle and tumble dry on low. Avoid using harsh chemicals or bleach as this may damage the fabric. Store them in a dry place when not in use to prevent mold and mildew. Since they're UV resistant, they can stay outdoors for a long time, but if you notice any dirt or stains, clean them promptly to keep them looking their best.
