Product review (5 stars): Love this stuff
My dishwasher gets "fishy" sometimes.  It also makes a disturbing grinding noise.  I just run a little Dishwasher Magic and *voila* it's smelling like a rose and quiet as can be!  You never think about cleaning your dishwasher, but just like anything else, it's gets dirty.  Afterwards, things come out cleaner and it really does run more quietly.
