Clean Door, What's That Secret You're Keeping?

I had a man in today who cleaned the oven. It's positively sparkling. I don't think the door has been that clean since the day we bought it.
Unfortunately, it's not going to stay that clean unless we live on takeaways. It's already splashed with pork casserole.
We have a very excited little Poppy tonight as she's going to France on a school trip tomorrow.
I'm not quite so excited and I won't be happy until she's safely back at home.
