Using our patent-pending Color Check Technology™, Sertun towels give you complete assurance that you are truly sanitizing hard surfaces!
Think of it as a quaternary ammonia (Quat) test strip embedded in a disposable foodservice towel.
Sertun towels change from yellow to blue when proper Quat levels are present in the sanitizing bucket and in the towel.
Have confidence you?’re sanitizing with just a quick glance into your sanitizer bucket!
As the towel deploys Quat, the color changes from blue to yellow, indicating there is not sufficient sanitizer in the towel.
By placing the towel back into your sanitizer solution, the towel recharges, and turns blue again. When the towel does not turn blue, it’s time to change the sanitizer solution.
