How do you get your oven clean, get all the bits of food out of the cracks and get the shelves and glass properly clean?
I've often used a company to do mine but can't afford this now so I bought an oven cleaning spray, left for 30 minutes but it's not cleaned it very well.
Can anyone recommend an effective product? Also, how often do people clean their ovens? I don't think we keep on top of ours enough which makes it even harder to get it properly clean.
