A:AnswerIt does not have a self-cleaning function (that would be cool). But it's pretty easy to clean. The inside is some kind of stainless steel, so it doesn't take much scrubbing to get it clean. Just use hot water and soap.
A:AnswerThese extra items didn’t come with mine either and I do not believe they are part of the package. You can buy them separately and in packages of different accessories.
