Germ-O-Gard uses breakthrough technology to safely kill bacteria and viruses on hard surfaces for up to 72 days!

Germ-O-Gard kills 99.9% of germs, including E. coli, Staphylococcus aureus, Vancomycin-Resistant Enterococci, Proteus vulgaris, K. pneumoniae, Pseudomonas aeruginosa, MRSA and countless other MDRO.

Germ-O-Gard can be used to protect against germ infestation on at-risk hard surfaces, including door handles, bench tops, phones, computer keyboards and mice, toilets (and toilet door handles), taps/faucets and more.

Germ-O-Gard is HACCP approved for use on food preparation surfaces in residential and commercial kitchens.

How Germ-O-Gard Works

A Hard Surface Disinfectant With True Residual Efficacy

Germ-O-Gard is a hospital grade hard surface disinfectant with genuine residual properties. Read on to learn why Germ-O-Gard is so effective in providing sustained protection against germs and why it is superior to competing products.

Germ-O-Gard is a unique hard surface disinfectant (HSD) with genuine residual efficacy. The product base uses a patented technology involving the co-polymerisation of hospital grade disinfectant (benzalkonium chloride) and a hydrophilic polymer (polyvinyl acetate or PVA.) In lay terms, the Germ-O-Gard protective film is an invisible, non-tacky plastic material similar to cured wood glue, which has a hospital grade disinfectant chemically attached to it.

On hard surface application, Germ-O-Gard's solvent base (isopropyl alcohol, ethanol and water) evaporates, leaving a durable residual film that incorporates the disinfectant. The dried film is insoluble in water and won't wash off or be negatively affected by the moisture typically present on human skin. Being plastic, the remaining film is scratch resistant and truly residual. Unlike competing products, Germ-O-Gard's existing residual film is easily removed from the surface when reapplied, because the plastic film is soluble in alcohol and a fresh film remains in place of the old one.

Other Hard Surface Disinfectants With Residual Efficacy Claims

Any disinfectant, if not rinsed off a surface, will continue to disinfect. Most disinfectants, however, are water soluble and if visibly left on a surface, are considered contaminants. Such products are required to be rinsed or wiped off. In fact, many traditional consumer oriented HSDs claim to leave no harmful residues, which also means they leave no beneficial residues to provide long term surface protection from germs.

HSDs based upon polyhexamethylene biguanide or polymeric biguanide (PHMB) claim residual efficacy, but in reality the remaining film is water soluble. Such film is easily removed by moist hands and will demonstrate minimal residual activity on, for example, a moderately used door handle. Furthermore, patents which have existed for many years in relation to these products do not mention residual efficacy as part of the patent.

Complicating the landscape further, there is a group of HSDs based upon organosilane technology. This technology is very old and, for many years, was considered too toxic to be worthy of consideration as a universally safe HSD. In recent times, organosilane technology has improved, and it is now not regarded as being toxic to humans.

Organosilane based products offer genuine residual efficacy due to their ability to form strong chemical (covalent) bonds with a hard surface. The covalent bond is so strong, however, that a film of organosilane cannot be removed from a surface. Multiple applications of these products result in a build up of multiple layers over time. So, if one application produces a sub-micron film thickness which is invisible, a weekly application will, over a relatively short period of time, potentially result in an unsightly visible coating. A film of just 20-50 microns is potentially visible to the naked eye.


The residual Germ-O-Gard film is water insoluble and tough, but easily removed and replaced. No other HSD with residual claims can match Germ-O-Gard's unique, effective and user-friendly properties.
