Wash by hand or you can use your washing machine at maximum 30°degrees. Choose a wool programme, don't forget to put your garment in a laundry washing bag, be gentle with the spinning and be abundant with water to rinse. Limit the detergents you use. Use powder and stay away from liquid detergent. If you insist on using a scale, 10g detergent for every kg of laundry will do the job. One scarf weighs about 200g. Never use softener! Dry your cardigan or stole flat, on a drying rack and preferably in the shade or inside. Steam your cardigan or stole if you think it's too wrinkled.
