Odor caused by fire and flood damage can be difficult to remove because it can affect almost every surface in the building or house. Extensive drying, cleaning and deodorizing are needed in most cases to restore the structure to safe and livable conditions. Odorcide Fire and Flood works through a process of counteraction and absorption to safely, but effectively eliminate the odor. Sold as a concentrate. Odorcide Fire and Flood is diluted with water and applied using sprayer and fogger applications.
