I was a bit disappointed. White residue left on the back of the oven, crumbs and a bit of grease left in the grove where the door closed at the bottom. Glass over the bulb still brown on it, and the top of the oven/grill looks either rusty or not cleaned. Also I think a bit more of the grease could have been cleaned out on the underside of the glass hob, but, as I’ve never had it professionally cleaned before he might not have been able to get to it. He was a lovely guy so it was a shame. I’d had my larger oven cleaned and it came up lovely on the top of it so I suppose I expected the same.
