Charlie’s Soap Laundry Pre-Spray works great on grease, grass, blood, tar, mustard, mildew, pine sap, wine and many more stains. There’s even a convenient Pocket Charlie’s size to use when you’re on the go. Apply the Pre-Spray to the stain, directly on the fabric as soon as you notice it. Rub the Pre-Spray into the stain and let it sit for a bit. Then wash with Charlie's Soap for laundry.
