How can you get pen stain off white shorts?

1. Blot the stain as soon as possible. Don't rub it, as this can spread the stain and make it more difficult to remove.

2. Try a stain remover. Apply a stain remover to the stain and let it sit for the amount of time specified on the product label. Then, rinse the shorts thoroughly.

3. Wash the shorts in the hottest water recommended on the care label. Add a heavy-duty detergent and a cup of white vinegar to the wash water.

4. Dry the shorts in the sun. Sunlight can help to bleach out stains.

5. If the stain persists, you can try a more aggressive stain removal method. This could involve using a commercial stain remover or a homemade solution like a mixture of baking soda and water. Be sure to test any stain remover on a small area of the shorts before using it on the entire garment.
