Rumpl blankets are designed to shed dirt and odor, however periodic washing is still needed for optimal performance. Use warm water and a non-detergent performance wash. Only wash your Rumpl in a front load washing machine; do not dry clean. You can also put your Rumpl in a micro-fibre laundry bag when washing. We strongly recommend air drying. If you must use a dryer, use the lowest tumble setting with the heat turned off. Excessive heat can damage your blanket.
