Product review (5 stars): No stinky washer!
I have been using this brand since day one with my new washing machine. Over here later it shows no signs of mildew or unpleasant odors.  Also does very well on stains and general cleaning.  The item that was delivered looked different than what I purchased in the appliance store but works just as well.  I'm not 100% convinced that it is real Excelsior, but I would buy it again in a heartbeat.
