Soaps are sodium or potassium salts of long-chain fatty acids. Hard water contains
calcium and magnesium ions. When soaps are dissolved in hard water, these ions
displace sodium or potassium from their salts and form insoluble calcium or magnesium salts of fatty acids. These insoluble salts separate as scum.
This is the reason why soaps do not work in hard water.

What is the main advantage of using detergent over soap?
Soaps and detergents behave differently in hard water. Soaps form a scum in hard water and this scum will not rinse away easily and is known to turn laundry a grayish hue. The insoluble film it leaves can leave a residue on your laundry much like you would see in a shower stall where hard water is present. Detergents react less to minerals in water and do not leave this residue. (3) If you live in an area where the water is soft, you will have more success with soaps, but even then a gradual build-up of calcium and magnesium ions (also called 'curd') will be left in the fabric of your diapers or any of your family's laundry over time. Another disadvantage cited with soaps is that they " . . .will deteriorate in storage and lack the cleaning power when compared with the modern synthetic surfactants."(4) Because of this, detergents have steadily become the cleaning agent of choice since World War II, because for all practical purposes - synthetic or not, they will leave your laundry cleaner.

Why are detergents more effective than soaps for cleaning in hard water?
The reason detergents are more effective than soap for cleaning hard water has to do with their ingredients and their function. Most detergents have cleaning properties that are able to combat hard water and mildew. The function of soap, however, is less complex. The function of water is to make water even wetter than what it is. This does not necessarily mean it contains cleaning properties.

Which hand soap works best?
All soaps work in essentially the same way. It is more a matter of preference. for instance, I prefer glycerine soaps because they are less harsh and seem to work well with our softened water--that is they rinse away cleaner.
