Why is it important to leave a sanitizer on the surface for the correct amount of time?

Leaving a sanitizer on a surface for the correct amount of time is crucial because this contact time allows the active ingredients in the sanitizer to effectively reduce pathogens to safe levels. Each sanitizer has a specific label claim that indicates the required contact time necessary to achieve its antimicrobial effect. When surfaces are not sanitized for the prescribed duration, the effectiveness of the sanitizer is compromised, and harmful bacteria and viruses may remain.

While improving appearance, creating pleasant scents, or preventing stains may be beneficial byproducts of cleaning practices, the primary purpose of using a sanitizer is to ensure that surfaces are safe for food contact and to mitigate the risk of foodborne illness. Therefore, adherence to the recommended contact time is essential for achieving optimal sanitation.
