The best way to care for your White Amber Clothing garment is to hand wash separately in cold water with a mild detergent. Wring out the water by hand , give it a good shake and hang in a shady area to dry.
If machine washing is necessary, it is a good idea to place your garment in a laundry wash bag or pillow slip to help protect the material.
All my garments have already been pre-washed and pre-shrunk. It is always better to wash separately or with similar colours, especially red.
