For those of you

who actually have had some staining from the iron in your water recently, we used to go to a cabin in Northern Wisconsin that had water with so much iron it was actually red. The stool had to be cleaned constantly due to staining and a product that worked shockingly well was called "THE WORKS." It took the stain right off.
Do remember this was from porcelain. Be sure to read the label for other surfaces.
