Washing is possible in the washing machine at home. When washing, use a mild detergent, use a laundry net, keep the water temperature below 30 degrees, wash weakly, and wash alone. If it is a single size, it can be washed in a washing machine with a capacity of 7 kg or more. To prevent the fabric from shrinking or warping, avoid prolonged soaking or rubbing. Do not iron, tumble dry at high temperatures, bleach or dry clean. For drying, hang it in the shade to dry.
