Whirlpool designers over the years have played with the design of those dispensers but one thing they never seem to have told the public was when you place Downey in the dispenser it should be mixed with only hot water, not cold. While having both Kenmore & Whirlpool over the years I found the best was probably around the 1999/2000 model year Kenmores that had that big top with the aqua color release ring, these where very easy to keep clean, I would clean it out with hot water, windex, and SHAKE!
