I ended up using a small, energy efficient dehumidifier and a fan to keep the air circulating and had great results. I used the 3M mildew remover to get rid of the mildew, which worked surprisingly well, and in combination with the dehumidifier, found that my condensation problems ended. I think that with this winter in FL being colder than usual, the condensation lasted longer, resulting in the mildew. Usually, in FL, only my AC is in use and that dehumidifies the air as it cools it. Hopefully, my problem is solved and I will just use the dehumidifier in the winters.
