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 Wiper. Sertun Towels Change From Yellow To Blue When Proper Quat Levels Are Present In The Sanitizing Bucket And In The Towel. As The Towel Deploys Quat, The Color Changes From Blue To Yellow, Indicating There Is Not Sufficient Sanitizer In The Towel.

Sanitizer indicator towels are designed to effectively eliminate the risk of cross-contamination and foodborne illness for food service establishments. Yellow towel turns blue when saturated with effective, quat-based sanitizer formula; turns yellow again when sanitizer is depleted. Towels can be recharged again and again.
