I come from a home that always had a Maytag suds saver. My mother had her Maytag for many, many years and was quite efficient with the suds saving feature. She taught me that it was not so much as being a "cheap", but that certain loads of laundry could easily have the water reused. That's probably why I like my wringers; I'm very careful with what I'm washing and when to let the water go. My mother never reused wash water more than a couple of times and we were always "clean kids" growing up. She, too, would always wash white underclothing (and diapers) in their own separate hot wash and never saved the water. But with a steady stream of sheets, bedding, towels, personal linens coming from a family of five, she knew what water could be reused. It helped with her household budget by conserving detergent, too.
For example, my bedsheets are white and I sleep alone; why not resuse good, sudsy wash water? The clothing I wash in that water gets clean and I've never embarassed myself by feeling that I'm wearing dirty clothing.
I agree it is a more "frugal" approach to laundry but if you're careful, why not? I take the time to separate my clothing not only by colorfastness, but by degree of use. I also soak my clothing if they are really dirty and start the wash with fresh water and never skimp with rinsing.
I'm not afraid to use water; it's one of cheapest commodities we bring in our homes but why not reuse some of the water, if it is reusable, instead of letting go back down the drain?
Thanks for letting me put in my $.02
