The manual for my oven says not to use oven cleaner. I've never had to though. I love my self cleaning oven. It works great. Nothing left but a little gray ash to wipe away. I use the cycle once a month, the day of guild meeting is my oven cleaning day. LOL. I don't wait until the oven gets dirty, that makes it smell when it's cleaning. What I do dislike with a passion is the oven door with the glass window. It's impossible to keep the glass from getting streaks between the panes.
