Shake the bottle well before use to ensure the solution is properly mixed. Apply a small amount of the stain remover directly onto the stain, making sure to cover it completely. Gently rub the solution into the stain using your fingers or a clean cloth, working from the outside edges toward the center. Allow the stain remover to penetrate the fabric for a few minutes. For tough or set-in stains, you may need to let the product sit for a longer period of time. After allowing the solution to work, launder the fabric according to the care instructions. Check the stained area before drying to ensure the stain has been completely removed. If the stain persists, repeat the treatment process or consider seeking professional cleaning assistance.
