If your shower has started spraying unevenly or the water pressure isn't what it used to be, limescale buildup could be the reason. Over time, minerals naturally present in water collect inside the tiny holes of the showerhead, restricting water flow. According to the report by El Cronista, there's an alternative to the usual baking soda and vinegar methods. Citric acid is gaining attention as a simple way to dissolve mineral deposits and help restore a more even water flow.
