<human>:  What is the best way to remove a stain from cotton?
<bot>: The best way to remove a stain from cotton is to treat the stain as soon as possible. Begin by pre-treating the stain with a solution of gentle detergent and warm water, followed by a dab of laundry detergent or dish soap onto the stain. Allow the solution to sit for a few minutes before rinsing with warm water. If the stain persists, you can use an enzyme-based stain remover to break down the stain, followed by a rinse with cold water.
