The best way to wash your kitchenaid knife set, whether steel or ceramic, is to put them under warm water and to give a little sponge with dishwashing liquid. Dry with a cloth and store them away. Even if the blade is stainless steel, do not let your knife soak in water. Firstly the water will eventually damage the steel, secondly, you will necessarily add other utensils in your sink, which will damage the blade and the edge of the knife.
