Have had the KitchenAid Oven with Aqua Clean for a month and used it maybe 4 times with minimal soiling. I'm now on my 6th time trying to clean it! The Aqua Clean is a joke! How can 40 minutes of steam clean an oven, especially when the inside is warm to the touch after this time! There has got to be some sort of oven cleaner that will work on this 'self clean' oven. Also ceramic top very hard to clean. Hate hate hate this oven!!!
