@Marc - You said, " lack of ventilation" that maybe my problem. The image attached is my closet doors. The doors are hallow. I think the doors are made out of pine. They're not your typical Florida louvered wood plantation doors. I should probably look into changing my doors to louvered doors.
@Jim - Currently, the clothes in my closet don't seem to have an odor, or I'm just used to it and it gets stronger once they've been packed in a suitcase. The suitcase Does Not have an odor. I've tried the suitcase in the sun. I've even washed & drying my clothes before a trip and still a musty smell. I have a new W/D, I use laundry detergent with no dyes. I dry my clothes with several fabric sheets. I clean my machine out once a month with clear vinegar. You name it, I do it & I've tried it. I think Marc is right about the lack of ventilation.
A week ago I was told my a mold specialist to keep my A/C on 76-77 during the day and at night leave it on 72-74. I personally like it on 72 because it helps me sleep better. Before I was leaving it on 74 during the day & 72 at night.
Marc & Jim - I really do APPRECIATE all your help!
