I have a 2 year old house and have been hanging my shower towel on a hook that is against a wall since I've lived in the house. Now, it seems there is a small amount of mold on the wall where the towel has been hanging. Right now it's just a dark discoloring. My question is, is this most likely mold and if so how should I go about getting rid of it? Thank you!
Some things to Know: The wall is painted with a flat paint; the fan runs all day after a shower.
Follow up question: If this is mold should there be concern that it is inside the drywall?
