<human>:  How can I remove a stain from my shirt?
<bot>: The best way to remove a stain from a shirt is to pre-treat the stain with a laundry detergent or spot remover. Soak the stained area in the solution for a few minutes before washing the shirt with a delicate cycle according to the care instructions on the label. Always check for colorfastness before proceeding. If you can, air-dry the shirt instead of using a dryer.
