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, ringlike 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.
