<human>:  How can I remove rust from a metal surface?
<bot>: The best way to remove rust from a metal surface is to use a wire brush to scrape the rust off the surface. You may also need to use a rust remover or a mixture of white vinegar and baking soda to dissolve any remaining rust. If the rust is very thick or resistant to removal, you may need to sand the surface with sandpaper or a sanding tool.
