Here is a four.oven AGA I cleaned last week. Alan had to go to a funeral so I did his afternoon job an AGA in Shepton Mallet. The AGA was in a barn conversion and was relatively straight forward. There was a stain just above the main oven door caused by smoke etc coming out of the main oven when cooking. The lady hadnt been using the fan as sometimes is needed on an electric AGA. The stain came off okay though on the door it was more difficult to get off. Sometimes these stains are just too difficult to get off. Anyway the end result was a gleaming AGA.
