The Science Behind Cardinal Clean

Cardinal Clean uses ozone, a potent disinfectant that naturally occurs in our environment.  Ozone is stronger than bleach and is often used to disinfect drinking water. The machine intakes oxygen and tap water then applies 4500V of electricity, allowing two-atom oxygen gas to rearrange into three-atom ozone gas to produce the ozone. Because of ozone’s unique structure, it disinfects molecules using radical oxidation instead of traditional oxidation used by chlorine bleach.

The Cardinal Clean solution quickly kills odors, stains, viruses, and bacteria, including E. coli, Salmonella, MRSA, C-Difficile, and hundreds of other common germs? It is  3,000 times faster and much stronger than bleach and chlorine-based cleaners without exposing you to toxins, carcinogens, or chemical residue.
