Why are my ice cubes cloudy? How do I get rid of the white flakes in my ice cubes?
Water freezes from the outside in, and the impurities inside the water are pushed towards the middle before they freeze. These impurities (minerals like calcium and lime) are harmless as long as you use drinkable water. Bottled and demineralized water has fewer impurities than tap water, so it will produce clearer ice cubes.
