Several issues ago we had a landlord with a mold smell problem in a camp. They called again and still had some residual odor. I did a little research and came up with a specialty product line that might be helpful. As you may know, I prefer not to suggest brand names because products often are cheapened down after they become popular. However, this line of products has a good reputation and they have a local dealer in Latham. It is called Star Brite and they have a complete line of mold and mildew and odor eliminators. Just GOOGLE Star Brite and check out their line of goods.
