I thought I was set on one but I've read it can melt things, be dangerous, give off fumes bad for asthmatics.seens like a lot of negatives just for a self cleaning oven.
However it's a function I assumed I didn't have to use unless desperate but a john Lewis oven I'm looking at, a review says it's beeping and reminding you to do it and it's annoying and when you do it you have to take the rails out etc!
