Thanks for the sugar soap mention. My oven is cleaned fairly often but could do with a thorough going over and the firm I contacted wanted £75.
Our cutlery drawer and those underneath it are currently spotless because DH accidentally knocked a milk carton over when the drawer was ajar. We spent all evening washing the contents and the tray, drying the drawer then cleaning with wipes, then discovered that the milk had managed to get into the other drawers (fortunately not the man drawer!) so they were cleaned out as well. I never realised I had 17 teatowels.
