Charlie's Soap Laundry Pre-Spray is a cost effective and environmentally safe way to deal with most stains. 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 – maybe 30 minutes. Don't be afraid to let it dry. Charlie's Soap Laundry Pre-Spray was designed to gently remove stains, not blast them off. 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 come out in the wash! Re-wet the stain with Pre-Spray just before you pop it into the wash. Feel free to repeat the process if necessary. Charlie's Soap Laundry Pre-Spray will not damage any fabric. (It might be a good idea to test for color fastness and follow your garment's care instructions, though.)
