Evidently your storage facility is not climate controlled. Not sure what your cases are made of, if they have a cloth cover bleach will bleach them out. I would spray with plain unadulterated bleach, wipe down and spray again, put in large garbage bags from home. Seal and transport that way. Then set outside. Does your new residence have a basement? Hope you're liking Ft. Wayne, last time I was there was DGD's graduation on 2013. I have lots of family there. What side are you living? Lots of family in surrounding areas also. Good Luck with the mold. You may have to Google for the best ways. Different kinds of molds have different treatment. If the mold has penetrated all the way through the case. the case is probably done. Sorry!
