Using Your Laundry Stain Remover Bar: Moisten the stained area and your Stain Remover Bar. Gently rub the bar into the stain for 20 seconds. Let it sit for a few minutes and rinse. Once the stained area is treated, wash as usual with our Kind Laundry Detergent Sheets. *Always test stain remover soap bar before using on delicate fabrics that require extra care when washing.
