Untreated wool is to be washed as seldom as possible in order to retain its natural lanolin. After wearing your woolen item, place it to “air-out”. If your woolen product becomes wet, just let air-dry or dry over a mild heat source. You’ll notice the cleansing smell of lanolin. The lanolin goes to work removing bacteria & odors, as the moisture evaporates away.
Wash your item when you feel it retains odors when dry or just seems less fresh. You may be able to go weeks between washings, even with daily wear. Items not worn directly against your skin or less often can go even longer between washings.
Wool is best washed by hand, in lukewarm water, with a lanolin-replenishing soap. Use just enough Lanolin Soap to keep the water sudsy. Stir your woolens gently in the water, then let them soak for 10-15 minutes. Rinse with lukewarm water, until water appears clean. If heavily soiled, you may want to first wash in shampoo or a mild detergent, then wash a second time with lanolin-replenishing soap. Gently squeeze water out of wool. Roll in a terry cloth or place in washer on spin only, to remove excess water. Give each item a quick, brisk shake to regain its shape, then lay or hang to dry on a dry heat source.
Placing natural wool in direct sunlight to dry may slightly discolor the natural wool.
