Baby alpaca is a remarkable wool. Hypoallergenic and soft as can be, it also provides natural stain and water resistant properties. To prevent spills from soaking in, simply blot away before they set. For tougher stains, you can wash your alpaca scarf with a mild detergent in cold water. Rinse well and lay flat between two towels. Roll up the towels to soak up the extra water and then lay flat on a fresh towel to dry.
