Chlorine bleach is the only thing that will counteract mold and mildew smell. You have to kill off the organism that creates the odor (mold spores/mildew) and chlorine will do that. Everything else will just attempt to cover up the odor and will not get at the source of the problem. I would take household bleach, put it in a trigger sprayer and spray all surfaces liberally. IF you have visible mold, wipe off the mold and bleach and then respray and let dry.

That said, I wonder if an O3 generator might also work as it would kill the mold spores (I think).
