What is the recommended contact time for QUAT sanitizer?

The recommended contact time for QUAT (Quaternary Ammonium Compounds) sanitizer is critical for its effectiveness in eliminating harmful microorganisms. A contact time of 30 seconds allows the sanitizer to effectively kill bacteria, viruses, and fungi on surfaces. This duration ensures that the active ingredients in the QUAT have sufficient time to act on the pathogens present, leading to a reduction in microbial load and providing a safe environment, particularly in settings like food service, lodging, and institutions. Adhering to this recommendation is essential for maintaining hygiene and preventing the spread of illness.

Other contact times such as 10 seconds may not provide sufficient exposure for effective sanitization, while 60 seconds and 90 seconds extend the process beyond what is typically necessary for QUAT sanitizers, which can be less efficient and might discourage proper sanitization practices due to longer waiting times.
