The Odor Bomb is economical while packing a punch. Using "active" chlorine dioxide versus "stabilized chlorine dioxide"  distinguishes The Odor Bomb from others. Not masking over the odor with temporary fragrances but rather breaking down the odor molecules. Tobacco, pets, food, marijuana, musty air and any other "mystery" smell!  No need to have the car running and problem solved in 20 minutes. Gone is the obnoxious, knock you off your feet chlorine or ozone smell. Eco-friendly, easyily transportable with a quick turnaround time. More appropriate for vehicles that are well maintained.
