The Cool Luxe Blanket is machine wash and dryable! It can be removed & drained as needed for cleaning, and we recommend doing so seasonally. The heavy weight linen blended fabric will get softer with each wash! Be sure to avoid harsh detergents and fabric softeners! These chemicals can build up on linen and have the reverse effect. Since the linen is blended with cotton you should avoid using high heat when drying- this may cause the fibers to shrink.
