Firstly, check washing instructions and colorfastness before washing your hanbok. If you are not sure, test a small area at the corner by dabbing with a wet cloth. Secondly, if you see colour transfer, stop the washing process immediately and ask for professional help. Also, some stains on your hanbok are visible and some are not. Hence, with ultraviolet light, we make sure the invisible stains are being captured. At Reward Laundry, we specialized in hanbok dry cleaning. Of course, we hand treat your hanbok stain for the best result.
