These dirty spots are “rub marks” left behind from rodents, in this case it was mice. The oil from the rodent’s fur will rub off on the surfaces they frequently travel and squeeze thru. Over time it leaves this residue that can often be mistaken as dirt, water or some other stain. When you know what to look for then the big picture becomes more clear on how rodents are traveling and getting inside your structure.
