As far as getting rid of odors musty or whatever, the best thing we have tried is cat litter. We had a freezer too go out one time and the fish left a terrible odor and I mean bad but we got the freezer fixed, washed it out good and let it dry out in the sun and the smell was still there so someone told us too put cat litter in it and I did even though I didn't believe that cat litter could help that smell but it did. Also we had some water leaks under my sinks and after they dried I had a musty smell and I put cat litter under there too and the odor was gone after a few days. Won't hurt too try cat litter as long as it is just the case and not the machine.
