Boiling water in a dish with lemon juice, put the oven on and leave it for an hour. The stuff will just wipe off.

Thanks, I'll try that. So, soak the interior of the oven with the boiling water and lemon juice without scrubbing, turn oven on to a high temp and leave for an hour? Or just put dish in the oven with the water and lemon? No Mr.Muscle or any of those products needed then, not even fairy liquid?
That's clean enough for at least another 3 years.
