A Safe And Eco-friendly Solution To Commercial Cleaning

Ensuring a safer, more effective solution to bleach that kills up to 99.999% of germs, including removing dirt and stains and the bacteria that causes odours, SQ 1 Development is proud to bring safer, cleaner spaces to you.


Combining the use of robots with cleaning solutions that contain environmentally safe and healthy sanitising and deodorising technologies, we utilise Tersano’s Stabilized Aqueous Ozone (SAO™) solution, which contains patent-protected technology to clean, deodorise and sanitise surfaces.

Backed by the world’s leading experts


A global innovator in toxic-free cleaning that has gone through rigorous testing by several Third Party laboratories worldwide – Tersano is the first company to receive the Green Seal 37 (for Industrial and Institutional Cleaners) and the Green Seal 53 (for Biologically Active Cleaning Products).


Tersano SAO™ products are already being used by leading establishments including Stanford University and McDonalds. Instead of relying on sanitisers and deodorisers that may contain harmful and toxic chemicals, this natural cleaning solution quickly attacks and destroys any contaminants that it comes in contact with, all while remaining completely harmless to people and the environment.

A revolutionary, toxic-free cleaning system


Tersano SAO™ uses advanced technology to convert oxygen in the air into ozone; infusing it into cold tap water to create a powerful cleaner, sanitiser and deodoriser without the use of chemicals.


The winning choice for residential and commercial cleaning that caters to a wide range of industries, the solution can not only be safely used on monitors, computer screens, office furniture, carpets and mirrors, but also various surfaces like marble and stainless steel. Utilising a chemical-free system and technology that acts in seconds, it effectively protects our spaces against viruses, bacteria, micro-organisms and fungus.


The stabilised aqueous ozone found in the solution can be dispensed using mop buckets, spray applicators and robotic scrubbers to provide a longer-lasting clean, and is suitable for use in healthcare, education, airports and office facilities.


Approved by the Food and Drug Administration (FDA), Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA), SAO™ reverts to water and oxygen upon usage with zero impact to our planet and waterways.




Tersano SAO™ is SQ 1 Development’s choice of cleaning solution to provide sustainable and effective cleaning to our customers on a day to day basis. This is especially important for spaces that experience a high footfall such as offices, banks, hotels and shopping malls.
