Cecil,
I have a part-time bathtub repair and refinishing business and I see a lot of bathroom fixtures that have iron stains or heavy lime build up.Some of the old farm houses smell like rotten eggs and the owners are unable to wash whites in their laundry for fear staining everything orange. The last few years most of the house in the county have switched over to rural water which has been filtered and treated getting rid of the iron but we still have really hard water.On the other hand,crushed limestone for my driveway is cheap.
