I did a quick search about the safety of self clean ovens today (bad for birds, but not cats). It seems that many people NEVER clean their oven. Now, I usually use a spray to avoid the smelly smoke from the self-clean, so my oven gets pretty cruddy between cleanings. Like, I'm not making pizza 'cause it's going to smoke cruddy. I'd guess my oven gets cleaned 3 times a year, and I don't use it very often. So how often do you clean your oven? And do you think that I could run the self-clean for only a couple of hours every month to keep it clean, as opposed to 4-5 hours every six months? I've read that the high heat sometimes ruins the electronic controls..any experience with that?
