Old house smells
Place dishes of vinegar around the basement. Vinegar will help break down the damp musty smell. It generally takes 2 to 3 days before you notice an improvement. Place an open bag of charcoal in your basement. Charcoal absorbs odours and dampness in the air. Be sure to change the bag every six months.
