Reddish to Brown stains may be caused by Iron and or Tannins in the water.
Iron is found in natural deposits and can cause many problems for anyone using water that has a high content of it.
Tannins are produced by decaying organic matter and cause a dark color in the water making it look like tea.
Both of these cause ugly stains that are difficult to remove.
