It would be much better if it was ironed after folding. We keep the clothes dry, apply "Blue Moon Down Jacket Cleaning Liquid" or "Blue Moon Hand Wash Special Laundry Liquid" directly on the stains, and let it stand for 5 minutes.
If the stain is serious, you can gently brush the stain back and forth with a soft brush or gently wipe the stain with a clean towel. After the stain is removed.
Dip a clean towel in water, wipe the place where there is laundry detergent, then rinse the place where the laundry detergent contacts with water, completely remove the residual detergent and dry it.
