Hard water stains often appear near sink drains, shower drains and in toilets. These stains are caused by a variety of minerals contained in the water supply. Over time these minerals build up on surfaces and create ugly looking stains. Manganese is one mineral that will create black, ring-like stains in a toilet. Removing the manganese stains takes a little bit of work and cleaning solutions that you must apply to the toilet bowl.
