We have a bathroom in our basement which gets very little use. Haven't been in it for a few weeks and found this tonight. (See photo.)
It has been raining heavy the last couple weeks, but there are no known water leaks or moisture issues. My questions:
1) is this mold or mildew?
2) best way to clean?
3) do I need to remove drywall?
Thanks. View attachment ImageUploadedByHome Repair1436499880.405164.jpgView attachment ImageUploadedByHome Repair1436499898.778564.jpg
