Remove hair, dirt and dried sweat with a stiff brush. Machine wash at 30 ° on a cool/wool cycle or hand wash. Use Lemieux Wool Wash (available from Horse Health). Ensure all hook & loop is securely closed prior to washing. Straighten/flatten cotton fabric after washing. Air dry near heat source. Never tumble dry. Avoid using strong fabric conditioners. Warning: In rare cases dye from black wool items may leach from wool items giving a slight blue tint. Staining of gray coats can occur.
