To remove ballpoint pen ink stains, you can try the following methods:
1. Rubbing alcohol: Dab a cotton ball or cloth with rubbing alcohol and gently blot the ink stain until it starts to lift off.
2. Nail polish remover: Apply a small amount of nail polish remover on a cotton ball and gently dab at the ink stain.
3. Hairspray: Spray some hairspray directly onto the ink stain and let it sit for a few minutes before wiping it off with a clean cloth.
4. Lemon juice: Mix lemon juice with equal parts water and apply it to the ink stain. Let it sit for a few minutes before rinsing with water.
5. Commercial stain remover: You can also try using a commercial stain remover specifically designed for removing ink stains.
Remember to test these methods on a small, inconspicuous area first to ensure they do not damage the fabric.
