I sooo need to do this. I haven't done it since we moved into the house 2 years ago. DH keeps reynold's wrap at the bottom to keep all of the drippy stuff away, but besides changes that every once in a while...the oven probably needs a good cleaning. We have the self cleaning option also, so I might give that a whirl.
I think it's crazy that my oven self cleans, and I haven't even done that in 2 years. I must be super lazy
