A Safe And Eco-friendly Solution To Commercial Cleaning

SQ 1 Development offers a safer and more effective solution to bleach for commercial cleaning. The solution kills up to 99.999% of germs, removes dirt and stains, and eliminates odour-causing bacteria.


We combine robots and eco-friendly cleaning solutions to sanitize surfaces with Tersano’s Stabilized Aqueous Ozone (SAO™) technology. This solution contains patent-protected technology for safer and healthier commercial cleaning.

Backed by the world’s leading experts


Tersano, a global innovator in toxic-free commercial cleaning, has been rigorously tested by Third Party laboratories worldwide. It was the first company to receive the Green Seal 37 and 53 for its industrial and biologically active cleaning products, respectively.


Tersano SAO™ products are already being used by leading establishments including Stanford University and McDonalds. This natural cleaning solution quickly attacks and destroys any contaminants, all while remaining completely harmless to people and the environment, without relying on harmful and toxic chemicals found in sanitizers and deodorizers.

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.


Catering to a wide range of industries, this cleaning solution is a winning choice for both residential and commercial cleaning needs. It can safely clean monitors, computer screens, office furniture, carpets, mirrors, as well as surfaces like marble and stainless steel. With technology that acts in seconds, this chemical-free system effectively protects our spaces against viruses, bacteria, micro-organisms and fungus. Additionally, it provides peace of mind for individuals concerned with harmful chemicals.


The cleaning solution’s stabilised aqueous ozone can be dispensed in multiple ways, including mop buckets, spray applicators, and robotic scrubbers. It’s a versatile choice that’s suitable for various industries, such as healthcare, education, airports, and office facilities, and it provides a longer-lasting clean.


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