Hand washing is recommended for this material. Do not machine-wash this piece! Wool is antistatic, so it retains neither dust nor odors. Often, simply airing it well is enough. Cold or lukewarm water only.
To machine wash your “hand-wash only” items at home, turn them inside out and slip them into a mesh bag designed to hold delicates during a wash. Machine wash them on cold with a mild detergent, using the gentlest cycle available. Remove your garments from the machine as soon as the cycle ends, and lay them flat to dry.
To hand wash, use a clean sink or basin. Fill the tub with cold water and add a small amount of a mild detergent, like Woolite. Mix until the water appears sudsy. Dip your clothing in and out of the mixture until it's saturated, then gently agitate it in the water, rubbing any soiled areas softly with your fingers to spot clean them.
When you feel confident that the garment is clean, empty the sink or basin and fill it with cold water, this time without soap. Dip the item in and out of the water until it's no longer soapy.
To dry the garment, lay it on a towel. Roll up the towel with the clothing inside, squeezing gently to remove water. Unroll the towel and move the garment to a drier area of the towel.
