Which is a better cleansing agent in hard water: soap or detergent?

Answer 1

Detergent is more effective in hard water and contains enzymes that chemically dissolve a wide range of stains. This is why detergent is better for laundry, but it is very drying to the skin. Soap is better for personal cleansing but it is hard to get a good lather with soap in hard water unless you get a soap with easy lathering qualities. Hand made soaps are true soaps. Most commercially produced "soaps" are detergent-based.
