I had an electrician at my place today and he had to pull my oven out to get access to the electrical wires for the oven. I was so embarrassed when he moved the oven out as the sides of the oven and back wall behind oven was filthy. It was greasy, oily with crusty bits stuck all over. We've only been living here for 6 months so it would not be just our cooking mess there.
The top of the cooktop was clean though. I am wondering whether anyone here in bubhub land ever pulls out their oven to give it a good clean and if so how regularly.
