Since Tersano was founded, we have kept millions of liters of cleaning chemicals out of our lakes, rivers and waterways.

Domino's Pizza locations have switched from toxic cleaning chemicals to SAO to clean, sanitize, and deodorize their stores.


It sounds like magic, but it’s proven science.

SAO Dispenser turns regular water and oxygen into a powerful cleaner, then turns it back again when you’re through. You’ll reduce chemicals of concern by 70% and enjoy 25% average ROI cost savings. Best of all, you’ll make the indoor environments you clean safer for everyone in them — including yourself.

Meet the SAO dispenser


Use PROscrub to complement your daily SAO cleaning regimen. As an NSF registered product, it is safe for use around food and has an SDS safety rating better than most deep cleaners and degreasers. It's particularly effective on grout and in other crevices where dirt and grime have accumulated over time.

Available in two formats — PROscrub RTU and PROscrub RTD.


Specially formulated for professionals, PRObowl is a fast, effective, and powerful multi-purpose descaler that easily removes the toughest calcium, hard water, lime, mineral and soap scum build-up that other products just can’t touch.
