I know it'll be impossible and the homeowner knows it to. She's running some dog business out her home and this is in her basement. The room I was standing in was the other half of the basement which is a normal living area with a living room and bedroom. I'm thinking she's just wanting to get the smell under control. So they won't smell it in the living areaI'd clean it first...maybe with something on the acid side.......then flood it with quats
knowing that the animal smell permeates everything in that room so completely getting rid of it will be impossible
