Did you happen to have a water pan in there that had water left in it when you closed it up? My Bradley did that one time and I had left a water pan full of water in it. Lesson Learned.

Not sure I would have cleaned the interior with Greased Lightning though. Even with a "burn in" session. I would have wiped it down with a strong vinegar/water solution. Run the "burn in" at as high a temp as you can get your MES.
