Hard water is water that contains calcium or magnesium mineral ions often in the form of carbonate. These ions do not pose any health threat, but they can engage in reactions that leave insoluble mineral deposits. Hard water mineral deposits, or scaling, is the precipitation of minerals which form lime scale. How to Descale? Fill the kettle with 1 cup of vinegar or lemon juice and 2 cups of water.
