The hydrophobic tail attaches itself to grime and dirt, while the hydrophilic head gets affixed to water molecules. Therefore, when the dirty clothes are put inside a washing machine or swished vigorously by hand, dirt is pulled away from the cloth and washed away in the water, leaving the cloth sparkling clean.

Answer:
Detergents are used to clean the dirt and oily stains on the clothes. The molecules of detergent are long in their structure. This molecule hold on to a water molecule on of its side and the oil molecule onto the other. Due to this, the oil mixes with water. It can easily come out of cloth along with dirt. The soiled clothes thus become clean due to detergent.
