How do I remove stain in bathtub?

As we winterize our cabin every year, this year was no different except when opening it back up for summer. Our plumber turned the water on but, the water dribbled from the tap leaving a huge stain near the drain. I have tried CLR thinking it would remove the stain. It did not. Any suggestions would be very much appreciated.
