Ecolab® Seratun Sanitizer Indicator Towels 61113-00-00, 150 Towel / Box

Sertun Towels are sanitation wipers that change from yellow to blue when submerged into a bucket of sanitizing solution prepared with appropriate Quat levels. As the towel deploys Quat-based sanitizer, the towel's color changes from blue to yellow, indicating there is not sufficient sanitizer in the towel. Submerging the towel into fresh sanitizing solution recharges it, turning it from yellow back to blue again. Towels can be recharged again and again until they no longer turn blue within a 6-8 hour shift. Discard after a 6-8 hour shift Towel will not turn blue unless sanitizing solution is prepared properly. Works with quaternary ammonia (Quat) only. Use within 2 years of the manufacture date stamped on the box.
