I second the exorcism. Sorry to hear of the mold, but it's a good thing you caught it early! If you use desiccant in the case (The stuff that changes colour with moisture) you can "recharge" it by baking it low in a toaster oven or microwave... you can do this a few times. Having desiccant in the case should slow down corrosion, mold and mildew. You can even get little paper stickers that change colour based on humidity, they might be handy as a quick spot check when opening the case. I'm paranoid about mold after dealing with it in a basement suite we rented once. We went away for a couple of weeks, came home and everything in the double closet was covered in mold... dresses, backpacks, super gross. Let us know how it goes... and good luck!
