I have been washing my laundry in cold water exclusively for the past 18 months. It was more a matter of saving money and being green than anything else. I use several different types of laundry detergent and wasn't unhappy with any of them but, since trying Tide Cold Water, I've noticed alot more suds in my washer and a nice, fresh fragrance to my laundry. I also only use about one-half capful instead of a full capful. Good Job, Tide!!!
