1. Minimum contact time is 1-2 minutes but longer contact times will improve sanitising effect on surfaces. While it isn’t necessary to wipe the surface after using Hawkeye Surface Sanitiser, it is recommended if the surface is to be used immediately, or if for food contact.

Ensure surface to be sanitised is clean from dirt or debris. Spray Hawkeye Surface Sanitiser liberally on the surface and allow to spread. Wipe clean with a damp cloth after a minimum of 1-2 minutes and rinse down the sink. Longer contact times provide better sanitising of surfaces up to and past 5 minutes. Clean any spillage that occurs with a damp cloth. Dispose of product by diluting in water.

Is Hawkeye Surface Sanitiser Dangerous?

No. Hawkeye Surface Sanitiser only has a mild skin irritation hazard. We don’t recommend getting it in your eyes because it might sting a little (see out answer about acids later on) but other than that it is very safe to use. Like any disinfectant, it is biologically active so care should be taken when using Hawkeye Surface Sanitiser.

Hydrogen Peroxide is used to Bleach hair. Will it bleach my hair or clothes?

No. Higher concentrations of Hydrogen Peroxide, at least 3% are needed to have a bleaching effect. Hawkeye Surface Sanitiser only contains 0.5% Hydrogen Peroxide. We have tested it on cotton fabric with no bleaching seen.

Why did you choose to use Hydrogen Peroxide in Hawkeye Surface Sanitiser?

To our knowledge, no products or surface disinfectants have been tested against Covid-19 so we used an evidence based approach backed by science to determine that hydrogen peroxide was the most likely to be successful against this virus. Hydrogen Peroxide is a broad spectrum disinfectant which has been used for many years for everything from sterilising wounds to medical equipment. It also has a very short conact time to sanitise a surface compare to other products.

Will Hawkeye Surface Sanitiser kill Covid-19?

We would love to say yes it absolutely will, but we are a science based company and the simple truth is no one has tested any surface disinfectants against Covid-19 because as a highly infectious human disease it requires a laboratory with strict quarantine controls and those laboratories are very busy currently for obvious reasons. We studied available data on treatment of coronaviruses and chose one of the two compounds that the scientific consensus regards as having the greatest of successfully sanitising a surface against Covid-19. See our Technical Information Sheet for more information.

What about Quats? Will they work for Covid-19?

The data for quats (otherwise known as quaternary ammonium compounds or QACs) is somewhat conflicting which we decided meant that they were less likely to be successful against Covid-19 than hydrogen peroxide. One thing that was clear is quats require a significantly longer contact time to be effective. See our Technical Information Sheet for more detail.

We’ve seen Surface Saitisers based on ethanol or alcohol. Whats the benefit of these?

Ethanol or Propanol based sanitisers are recommended for hand sanitation as they evaporate quickly and don’t leave a residue. However, data suggests that 70% solutions of these require at least 1 minute contact time for hard surface sanitising which is difficult to achieve because the alcohols evaporate so quickly. To work on a surface sanitisers need contact and time with the microbe which can be a challenge to get right with alcohols. The other important consideration is flammability. Both ethanol and propanol are highly flammable and can form explosive concentrations in the air easily when they evaporate. Cleaning a large surface in an enclosed space could potentially reach the explosive concentration in the air quite quickly.

Why do we need to clean the surface before using?

In order for hydrogen peroxide (or any disinfectant) to work it must contact the microbe we are trying to eliminate. A dirty surface could have microbes residing under the dirt, so spraying a disinfectant on the top of the dirt will not contact the microbes. Trying to use a disinfectant as a cleaner will simply smear the dirt and microbes around on the surface and it is highly likely some microbes will not be contacted and will remain alive. The best approach is to use a surface disinfectant on a cleaned surface to ensure it contacts the microbes to kill them.

Can I use a cloth to spread Hawkeye Surface Sanitiser over a surface?

Yes. In order to disinfect a surface you need contact for an appropriate amount of time with a microbe. Provided you get both contact and time (1-2 minutes recommended) after spreading the sanitiser you will still getting a sanitising function from the product.

I have noticed a visible residue on the surface after using. What can I do about this?

The residue is similar to what remains after cleaning a surface with a soapy water solution and is what remains of the spreading agents in Hawkeye Surface Sanitisier. This can either be removed with a damp cloth or buffed off with a dry cloth.

Do we need to shake Hawkeye Surface Sanitiser before each use?

One component in the product can separate out over time so we recommend shaking before each use. We are currently working on a version of the formulation which will not require shaking and will advise on our website when this has been released.

Will Hawkeye Surface Sanitiser damage surfaces it is applied to?

We have tested Hawkeye Surface Sanitiser on a large variety of surfaces including stainless steel, kitchen benchtops, fabric, vinyl flooring, office furniture, acrylic paint with no staining or damage. After it dries the vast majority of surfaces are easily cleaned with water, but we have found some lower quality acrylic paint covered surfaces may need washing with a soapy solution to completely clean the residue after it has dried.

We see Hawkeye Surface Sanitiser is acidic and some products promote they aren’t. Why?

Hawkeye Surface Sanitiser is acidic but it is less acidic than commonly found foods such as vinegar and lemon juice. Hawkeye Surface Sanitiser works better if it is a weak acid, and we won’t compromise on performance just to apply an unnecessary label such as ‘pH neutral’. An easy rule of thumb is don’t put the product anywhere you wouldn’t put lemon juice, so it might damage mild steel or aluminium and it will sting a bit if it gets in your eyes.

We’ve heard some people promote taking sanitisers and disinfectants orally or by injecting to treat conditions. Can we do this?

NO! Never ever consume or inject a sanitiser or disinfectant. Regardless of their hazards these products are biologically active and will likely cause damage to you if you take them internally, potentially resulting in death. Always follow label directions. That goes for any product, not just Hawkeye products.

We’ve noticed Hawkeye Surface Sanitiser sometimes has an odour and sometimes doesn’t. Is it still good to use?

Hawkeye Surface Sanitiser has chlorine and vinegar like odour when it is freshly made but this dissipates over time as it sits around in its packaging. We believe the chlorine odour is chlorine from the town water supply used to make the product being released by the hydrogen peroxide. Regardless of odour Hawkeye Surface Sanitiser still contains the necessary amount of activated hydrogen peroxide to be effective so you can use it with confidence.

Hawkeye Surface Sanitiser uses stabilised hydrogen peroxide instead of commonly found quaternary ammonium compounds (quats or QACs). Renovo Technologies considered doing another QAC based product for Hawkeye Surface Sanitiser but ultimately decided that hydrogen peroxide was a better solution. Why use hydrogen peroxide instead of QACs?

Mode of Action

QAC compounds are a large family of chemicals that all have a quaternary ammonium group in common. They usually have a chemical name ending with ‘…ammonium chloride’ or ‘…onium chloride’, eg ‘didecyldimethyl ammonium chloride’ (DDAC) or ‘benzalkonium chloride’ (BAC). The mode of action of QACs is still poorly understood but it is often characterised as charged spikes that can penetrate the cell membranes of microorganisms.

Hydrogen peroxide has been shown to be effective against all forms of microorganisms, including dormant forms with known high resistance such as bacterial spores and protozoal cysts, and also infectious proteins such as prions depending on the specific use of the chemical. As a strong oxidiser, the basic mechanism of chemical oxidation of cellular components provides a broader spectrum of control than other modes of action. However, like QAC, the specific mode of action is poorly understood. Hydrogen peroxide is highly reactive which advantageously allows it to rapidly eliminate microorganisms and also degrade rapidly to benign adducts. The components in Hawkeye Surface Sanitiser will degrade quickly to water, carbon dioxide and oxygen when diluted further in water making it safe to the environment.


There is conflicting data available around the effectiveness of QACs, the concentration and the contact time needed for control of microorganisms. Some data suggests that QACs can be effective against coronaviruses with a contact time of at least 10 minutes, while other data suggests that QACs aren’t effective against coronaviruses1. Likewise, data exists that suggests QACs may not be as effective in treating robust bacteria such as biofilm formers2. The same studies show that hydrogen peroxide is an effective sanitiser for coronaviruses with a contact time of 30 seconds, is also effective against the same robust bacteria. One of the reports recommends hydrogen peroxide as the sanitising solution for medical equipment over QACs.


QACs have a wide variety of hazards, depending on the QAC being used. Common hazards are acute toxicity, skin sensitisation, eye and skin corrosion and toxicity to the aquatic environment. Diluted or ready to use QAC products have reduced hazards but irritation, sensitisation and toxicity hazards (both aquatic and mammalian) are still commonly listed on various QAC products. QAC products are also under reassessment by a number of regulatory agencies including the NZ EPA due to concern over hazards.

In concentrated form hydrogen peroxide has a wide variety of hazards. However, when diluted to its ready to use form of 0.5% as found in Hawkeye Surface Sanitiser the only hazard listed is a mild skin irritant.

Personal Protective Equipment

While no specific personal protective equipment is required for the use of Hawkeye Surface Sanitiser, it is recommended as best practice to use standard PPE (eg eye protection, gloves and respiratory protection) if large quantities are being applied because the risk of large exposure is increased.

Effect on Surfaces

Hydrogen Peroxide is well known as a bleach at concentrations above 3%. Hawkeye Surface Sanitiser has been tested against a variety of surfaces including stainless steel, painted surfaces, melamine benchtops, carpet, vinyl flooring and fabrics with no damage to these surfaces. Mild steel may exhibit some corrosion if exposed for a period of time. It is impossible to test every type of surface including all types of paints and coatings so caution is advised and a test on a small area of the surface prior to using the product may be warranted if at all concerned.
