Black Water Damage Mold?
I recently purchased a home and the garage has a hose attachment preseumedly so you can wash the car in the winter. I've noticed that there's (what I can only assume is) light water damage on the surface of the plywood around the entire room (looks like splash marks and such.)
My question is, it's mostly black. Almost like it was stained.
Without seeing a photo, is that likely mold and should I do something about it? (Perhaps I should try and get some photos!)
