In order to maintain your knit sweater, we recommend tou to handwash it or wash it in a washing machine at low temperature (20° at least). If your sweater is made of wool, it is better to use a wool washing liquid and to wash it with delicacy without pull the knit at the risk to deform it. Do not let your sweater soaks and rinse it slowly. For a washing in machien, put your sweater in a cover or a net to protect it from the washing machine drum.
