Using your Santiago Steel Super King Quilt Cover Set is easy. Simply put it on your super king - sized bed to instantly upgrade its look. When it comes to cleaning, it's best to follow the care label instructions. Usually, a gentle machine wash in cold water is a good option. Avoid using harsh detergents as they can damage the fabric. After washing, tumble dry on a low setting. To keep it looking its best, iron on a low - heat setting if needed. This will help maintain the smoothness of the cotton sateen and the crisp look of the twin merrow stitch stripes.
