Expert Answer
Clothes become dirty when something get spilled on it or because of human precipitations dirt comes and attaches itself in the pores of the clothes.The cleansing action of soap is determined by its polar and non-polar structures in conjunction with an application of solubility principles. The long hydrocarbon chain is of course non-polar and hydrophobic (repelled by water). The "salt" end of the soap molecule is ionic and hydrophilic (water soluble).
