My current oven (purchased in the early 80's) has had the oven racks left
in during the cleaning cyle for almost 2 decades. And aside for dis-
colouring and a slight warping, nothing else has happened. Large turkeys,
hams and lasagnas have been cooked with no problems. But it is difficult to
change the oven rack to different positions due to the slight warping.
