H2O is an amazing liquid. It is useful for manufacturing, transportation, firefighting,energy production, cooking, agriculture, recreation and of course, drinking. Wateralso has some unique qualities that make it an excellent cleaner.
Water is a polar molecule, meaning it has both positively and negatively charged sides. Without going into too much chemistry here, this means that water can attract to and surround a great variety of substances. Think about everything that water can dissolve or dilute and you beginto understand why water is referred to as the “universal solvent.”
But water can’t dissolve everything. Dirt and grime usually adhere to skin, clothing, and other surfaces by combining with body oils, cooking fats, lubricating greases, and similar substances.
