Tide To Go Stain Pen is a compact stain-removal applicator intended for immediate treatment of fresh fabric stains. To use, extend the pen tip and apply directly to the stain, blotting gently with a clean cloth. It works best on recent spills to help prevent permanent setting; always test on an inconspicuous area first. Not recommended for delicate fabrics such as silk or leather. Store upright with cap closed. For specific care instructions or misuse guidance, refer to the product packaging.
