While sheepskin numnahs need a little care, they’re easy to clean. Before washing, remove hair, dirt, and dried sweat with a stiff brush and close fastenings. We’d advise washing your numnah in a wash bag to protect the fabric. Hand wash or put in the washing machine at 30 degrees on a cool or wool cycle. You can use LeMieux Wool Wash, but avoid using strong fabric conditioners. Straighten or flatten the cotton fabric after washing and air dry away from any heat source. Never tumble dry.
