CSG's Newest Green Cleaning Solution!

Updated: Jan 24

20- October 2020

Brea, CA—As apart of both CSG’s technology and green cleaning initiatives CSG is beginning to roll out Tersano’s Stabilized Aqueous Ozone (SAO) machines to our job sites. The SAO machines turn regular water and oxygen into a powerful cleaning solution. The solution that is produced can be used as an all-purpose chemical cleaner, disinfectant, sanitizer, and deodorizer, with no rinsing required. It is safe to use on all surfaces as well.

The best part is that after 24 – 48 hours the chemical break down in drinkable water. Therefore, not leaving any harmful residues or any environmental impact. This product even has the efficacy data to prove it can kill the Coronavirus. Thus, giving you the peace of mind that your facility is thoroughly cleaned with no detriment to your employee’s health.

In addition to the cleaning and health benefits that Tersano’s offers, it is also far more inexpensive than purchasing cleaning chemicals and can result in cost savings directly to our clients. Tersano’s has received multiple awards as well as has under gone rigorous testing in a hospital environment.
