Once GermFree24 has dried, the one single application will provide protection for up to 24 hours. In fact, we say Zoono GermFree24 ONLY lasts for 24 hours not because the product stops working but because skin naturally exfoliates and when it falls off, it takes the Zoono with it.

Spray GermFree24 directly on to the hands until the hands are moistened. Rub hands together until dry.

Zoono has been proven to provide long-lasting antimicrobial protection against a wide range of microorganisms, including bacteria (e.g., MRSA, VRE, salmonella, E. coli, listeria), viruses (e.g., norovirus, swine flu, influenza, herpes simplex type 1), fungi and mold. For a full list, please see our Safety & Effectiveness page.

Zoono kills mechanically. When Zoono is applied (and allowed to dry), it leaves a thin bonded film that, at the nano level, resembles millions of sword-shaped road spikes – spikes that attract and kill bacteria. Because Zoono does not change during this process, one single application can last for a month or more (depending on the surface and the application).

Zoono is a totally unique antimicrobial product. Zoono does not kill bacteria by poisoning. Instead, it creates a hostile barrier that resembles a “bed of nails” that punctures and kills microbes when they come in contact with it. This means that there is no possibility of bacteria building up an immunity (i.e., no super-bugs).

Zoono does not use chemistry to kill germs – it uses physics. Zoono permanently bonds to surfaces and sets up a nano-molecular layer of pins which create a hostile barrier to germs that physically impale and destroy germs that come in contact with the Zoono layer. This method of action is why Zoono can keep working for up to 30 days on surfaces.
