Be assured Zoono does not contain any harmful chemicals. Zoono is less harsh than vitamin C and coffee. When applied to a surface, Zoono leaves behind a mono-molecular layer that bonds to the surface forming a positively charged barrier. The positively charged molecules attract and pierce negatively charged pathogens.  This causes the pathogen to break up with an elimination effect (Including COVID-19). The layer lasts up to 30 days on surfaces no matter how many times that surface is touched.
