Hard Water

 

Hard water is created when water passes through rock formations and pick up calcium and magnesium. Hard water is easy to spot; it leaves a bathtub ring made up of hardness minerals and soap. This scum collects on shower walls, clings to hair, clogs skin pores, and make house cleaning extremely difficult. Hard water deposits also clog pipes, cause water heaters to operate inefficiently, and increase the maintenance on water-using appliances.
