Weighted blankets and duvet covers are all machine washable, but respect the washing machine's weight limits. We therefore recommend hand washing for this reason, as not all washing machines can withstand the weight of the blankets. If you decide to wash the weighted blanket in the machine, first remove the duvet cover and wash the blanket alone in the machine with lukewarm water without spinning. Let the blanket dry on a level or hanging surface. Weighted blanket is also possible to dry clean. Duvet covers can be machine washed in lukewarm water and spin dry.
