Bac-To-Zero. Sanitizing Odour Eliminator BAC-TO-ZERO® Full Control is a revolutionary process of eliminating odours, germs and bacteria in one simple step. It works by creating a mist that envelops the entire interior of the vehicle with our proprietary formula. It removes odours right in its the source by eliminating molds and bacteria, attacking them and slowly breaking down their chemical composition and starving it of neccessary oxygen before it can multiply. BAC-TO-ZERO® works very well with air-conditioning systems because it can circulate with the natural air flow of the system. Revolutionary mist system Complete interior coverage Kills bacteria fast
