I use a trouble light to remove the musty smells and have had great luck with that. You position the light inside the cases making sure it does not touch anything. My understanding is that the heat kills the mold. I leave it and reposition it so it faces all sides for several days but it cannot touch any sides. I believe the low heat is what takes care of the smell. I close the lid partially as well. I am very careful! So far have not burned anything but I do use a low watt bulb and that maybe is why it takes a little longer sometimes. As you can see I'm NO photographer! Hope this helps. You can also hang it from the cord in the Bernina case leaving an opening for heat to escape if need be.
