To use your Santiago Charcoal Quilt Cover Set, simply put it on your king - sized bed. First, open the quilt cover and place your quilt inside. Make sure to align the corners well. When it comes to cleaning, it's best to follow the care instructions on the label. Usually, you can machine - wash it in cold water on a gentle cycle. Avoid using harsh detergents as they may damage the fabric. For drying, tumble dry on low heat or air - dry. This will help maintain the softness and quality of the cotton sateen. Also, try to store the set in a cool, dry place when not in use to prevent any mold or mildew growth.
