Polar Night blankets and duvets are all machine washable, but please note the weight limits of the washing machine. For this reason, we recommend hand washing your blanket, as not all washing machines can handle the weight of a blanket. If you decide to machine wash your blanket, remove the duvet cover first and machine wash it alone in lukewarm water at around 40°C without spinning. Allow the blanket to dry flat or hanging. It is also possible to dry clean a quilt. Duvets can be machine washed in the normal way using lukewarm water and spin drying.
