I am currently having my oven cleaned by a professional oven cleaner. That is his main job...to clean the ovens of those who cannot be bothered. I will admit my oven is disgusting, I mean really gross, but probably no worse than anyone else who cooks but doesn't have time to clean it. However, upon inspection the man appeared shocked and disgusted!! Not even an act to justify his existence, genuinely shocked. I mean seriously, if your oven is bad enough to call in a pro cleaner, what does he expect? Or do people pay £40 to get thier already clean ovens cleaned? Am IBU or is he??
