What Causes Hard Water Spots?
Hard water spots are caused when water with a high calcium carbonate content evaporates. The calcium remains behind, and is the cause of the white spots that are known as hard water spots. Hard water is classified as water with a one milligram of calcium carbonate per liter of water. This is sometimes referred to as one degree American, or one part per million. Hard water is naturally occurring and is typically found is mountainous areas or locations with a low water table. Hard water has a high mineral content, comprised of calcium, magnesium, metal ions. It can also include biocarbonates and sulfates. The calcium is often in the form of limestone, chalk, or calcium sulfate. The most common source of magnesium is dolomite and metal ions can be derived from metal water pipes. Many people report water spots on dishes removed from the dishwater, but not on dished washed by hand. Very hot water will result in an increased volume of water spots. An increased number of spots are created wit
