I've been using it since seeing scottwax's recommendation a while back and have been pleasantly surprised with how well it works. Well, i just ran across this today, woolite now makes a low sudsing formula for high efficiency front loaders. Since sudsing seems to be one of the more common complaints (granted, some people need to fix their dilution) this may be the ticket. I'll pull a floor mat out of my car and tell you how it works tomorrow.
