<human>:  How do I get rid of a rust stain?
<bot>: One way to get rid of a rust stain is to use a mixture of white vinegar, salt, and baking soda. Start by mixing the white vinegar, salt, and baking soda in a bowl until a paste is formed. Then, apply the paste to the rust-stained area and let it sit for 10-15 minutes before wiping off the paste with a wet rag. If the stain persists, let the paste sit on the stain for an additional 10 minutes and then scrub gently with a soft brush. Finally, rinse the affected area with warm water and then clean with a stain remover.
