What is being used to help water wash away greasy dirt?

Surfactants, commonly found in detergents and soaps, are used to help water wash away greasy dirt. These compounds reduce the surface tension of water, allowing it to better penetrate and break up greasy substances. Additionally, the hydrophilic (water-attracting) and hydrophobic (water-repelling) properties of surfactants enable them to encapsulate grease, making it easier to rinse away with water.
