Possible mildew in a closet - what do I do?
I live on the 3 floor of a condo building on the ocean in NY. I have a walkin closet packed with clothes, shoes, etc. that has one wall next to a bathroom and the other is an outside wall. The outside wall had all bricks and insulation removed for about a year (they did the entire building) and now all have been replaced. My wife noticed that three of her rarely used outfits had white powdery stains all over their lining. There is no odor at all.
What do I do? A cursory look shows no stains on the walls nor on other clothing. Should I remove all clothing items for a closer look at them and the walls? Should I do anything inside the closet? Bleach? Heat lamp? Dehumidifier? Some commercial product?
Thanks for input.
