Mild detergent in cold water. Don't soak too long and don't wring or twist. Do a quick swish through the soapy water and run in cold water until the detergent is rinsed away. Then take the scarf and place on a towel and roll up in the towel to squeeze out the excess. Lay the scarf flat to dry. Secret to maintaining longevity with the color is not to soak too long.okay, I did buy a scarf from ebay and when I got it I was shocked at how stiff it was. How do I wash it to soften it up. I love the feel of my newer scarves
