<human>:  How do I remove rust stains from clothes?
<bot>: The best way to remove rust stains from clothes is to mix equal parts white vinegar and water and apply it to the affected area, then scrub gently with a soft bristled brush. Allow it to sit for 10 minutes, and then rinse it with cold water. Repeat this process until the stain is removed. If the stain persists, try mixing lemon juice and cream of tartar into a paste and apply it to the rust stain. Leave the paste on for 30 minutes and then rinse with cold water.
