We developed THE LAUNDRESS Wash & Stain Bars as an alternative to removing tough stains on your sweaters, delicates and more. This product can be used for spot cleaning, hand washing or laundering on the go! The Wash & Stain Bar is best when used for working on stains found on collars, cuffs, small straps & other tricky areas. Not recommended for wine or tea stains. They're not just for washing...place in a drawer, closet and luggage. Airplane friendly.
