I just can't face it. I did actually buy some Mr Muscle oven cleaner but the instructions made it sound so dangerous I shoved it to the back of a cupboard.
When we moved in I loved the almost new and completely spotless range oven in the kitchen - and for a few weeks I would wipe it round after using it. But over time it's got pretty crusty and now I can't see through the glass door anymore.
But the oven cleaner looks so toxic....
