Yay Kath! Glad things are going well now. The only thing I have had success using to clean stuff like that are those little squares of hard plastic they sell in the kitchen department of some mass retailer stores. They used to be almost exclusive to home sales of pampered chef, used to clean their stoneware, but they are now available in lots of home departments. They are hard, but they are plastic, so they don't scratch, but can really scrape off burned on things that scrubbers just won't budge. I think I used to set my oven just above warm for sauce reduction, it came with an insert that removes for cleaning which helps, trying to clean the whole thing without ruining the electric portion is a nightmare.
