How do I remove water stain from terrazzo floor?

The cast iron water pipes developed a slow water leak in the bathroom. The water seeped under the walls and sat for an unknown amount of time before it spread out onto the floor. There is a brownish stain along the quarter-round molding that needs to be cleaned before installing new molding.

    Try a product called AWESOME, it is sold at Dollar General. I used it on a sweater to remover rust spots. It is an all purpose cleaner. Good luck.
