If you want to wash delicate sweaters (such as cashmere), hand washing is the safest option. Fill a basin or sink with warm water and add a small amount of wool detergent. Gently spin the garment in the water, then rinse thoroughly and lay flat to dry. If you use a washing machine, make sure you select the wool washing program and set the temperature to no higher than 30°C. Never put wool clothes in the dryer, as the heat will cause them to shrink and warp.
When storing, choose a good breathable storage bag for the sweater, which helps prevent dust and odor infestation. Choose natural materials to ensure air circulation.
When storing, keep away from direct sunlight and choose a cool, dry environment to avoid color fading.
Sweaters of different colors and materials are best layered to reduce stacking time and help maintain shape and elasticity
