Yes, it made me feel better to know we alone don't have a particularly icky problem! I emailed Bosch and they recommended Bi-carb soda. I use this to clean my bathroom. I cannot actually remember if I tried it! So I am going that route before resorting to the bleach. My SO says we should have dragged it outside today (41 deg C) and left the door open to cook it. That probably would have worked but was all too hard. lol.
