We're leaving it behind for the vendors. They are paying us £50 for it. It's a few years old. Electric fan oven. Having been brought up with an AGA I am not good at frequent oven cleaning 
I have oven-prided it and it's better. I've had a good scrub at the racks afterwards and they are mostly clean. I have had a go at the top with hob cleaner.It looks cleanish but not new.
Is that good enough do you think?
