Pull a glass from the dishwasher. If it looks spotty, cloudy, or like it’s wearing a permanent thin layer of frost, that’s calcium carbonate laughing at your rinse aid. These spots are mineral deposits left behind when hard water evaporates.
It’s not just glasses. Your shower doors, faucets, and even that fancy kettle might develop a white, crusty scale. Think of it as a tiny, unwanted mineral art installation in your home.
Fun fact: Hard water is actually full of healthy minerals like calcium and magnesium. The problem? Your appliances and skin don’t want them in such high doses.
