How do you wash a baseball cap?
That's helpful. What if the cap has stains on it?
If your baseball cap has stubborn stains, you may want to pretreat them before washing. You can use a stain remover or gently rub the stain with an old toothbrush and a bit of laundry detergent. Just be sure to rinse the cap thoroughly before washing!
