Dispel eliminates odors such as hydrogen sulfites and methane. It does not hide or mask the odor; rather, it completely eliminates even the most noxious odors in wastewater and sewer plants, lift stations, landfills, garbage trucks, dumpsters, and even port-a-potties. It completely neutralizes and cancels out the source of the odor, leaving behind a pleasant bubble gum fragrance. Cherry and lemon scents are also available. Dispel is completely biodegradable.
