Head to Dollar General (or similar) and get a bottle of "The Works" for removing calcium/lime/rust bathroom cleaner. You could also grab CLR if unavailable. For small areas, take a strip of tshirt cloth and twistie-tie it to the area to be treated. Take the liquid and soak the cloth. Keep it moist over a period of 8-10hrs. Remove the cloth and rinse well. Amazing stuff.
