Over Thanksgiving, I was discussing water with Ordinary Spouse and my in-laws, and was astounded to discover that they prefer soft water for bathing, showering, and washing clothes. Their argument (if I recall correctly) was that soft water requires less soap. My preference had always been for hard water, because I liked the “squeaky clean” feeling of things washed in hard water.

So I’d like to hear from you (and feel free to add comments explaining your reasoning).
