The purpose of soap or detergent in washing is to reduce friction between the oil drops carrying dirt particles and the water so that they may mix with each other. All the methods that have been suggested loosen the bonds between the dust or oil particles and fabrics of clothes. The agitation helps in washing the clothes.
