I remember seeing articles in Laundry Today about the wonders of Ozone washing... a few years ago... but not much since. The article was a bit puzzling because it spoke of treating the post-rinse water... I guess if you're going to re-use it, ok, but who wants to re-use rinse water in the first place?
I also recall seeing a counter-top ozonated water generator at Costco about five or six years ago. It was pricey - about $150 - but it touted how ozonated water could kill all germs in a few seconds while a chlorine bleach solution would take 15 minutes to an hour to do the same. That product also had a short appearance in the stores - haven't seen it since.
