Charlie's Soap - Pre-Spray 16oz. 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, 30 minutes or so. You can let it dry.
The Laundry Pre-Spray will separate the stain from the fabric. The treated area will look like the stain is spreading and that means that it will wash out.
Re-wet the stain with Pre-Spray just before you pop it into the wash. Repeat the process if necessary. The Laundry Pre-Spray will not damage any fabric but it is always a good idea to follow your garment's care instructions.
