Hi, the main sewage drain under my house developed a leak and although now fixed I am left with the smell of sewage that I would like to neutralize safely. I spread an household antibacterial solution (Lysol) to take care of the bacteria and it is reasonably dry, although a little damp down there. My plumber recommended I spread Lime under the house. Are there any powder products I can spread down under the house crawl space to neutralize the odor without harming the occupants? Calcium Oxide but I read a bulletin from NJ saying this is harmful for the lungs. Many thanks for a speedy response.
