Washing any of your woolen clothes will clean them but can shorten their overall life. To make sure they last as long as possible you need to know how we can take care of woolen clothes without washing them. If you find a new stain on a piece of your woolen clothing blot it with a cloth of water and soap to help remove the stain. After wearing your woolen clothing, allow it to air dry in the sun before putting it back in your cupboard if it's good for another wear (e.g. hasn't got dirty or sweaty).
