Now to explain, chemically, how soap works to clean things. Fats mixed with strong bases are hydrolyzed into fatty acids. Fatty acids have the very useful property of having one end that mixes well with water (it is hydrophilic, or "water-loving") and another end that mixes well with oils and fats (it is hydrophobic, or "water-hating"). The part that mixes well with water is the "acid" part.
