Answer:
Detergent cleans by causing a chemical reaction with water that removes dirt out from clothing.
Explanation:
Detergents have the property to remove dust and oily particles which normal water cannot.
Detergents have a long chain of hydrogen and carbon atoms, as well as the ionic group that dissolves in water. The hydrocarbon part (hydrophobic / water-hating /water-repelling) is the tail and the ionic part (hydrophilic / water-loving) is the head of the detergent's structure.
The hydrophobic part of the molecule is repelled by water but is attracted to oil and grease. The hydrophilic part of the molecules is attracted to water. The soapy solution then gets clear of the fabric and we rinse it off with water.
