Have you ever used disposable wipes outside of a grocery store to sanitize your shopping cart? With the flick of the wrist, sanitizing products are applied and quickly tossed into the trash as you proceed with your shopping. This little-known, but crucial step in the disinfecting process is called dwell time, which is the amount of time a product must remain visibly wet on a surface to properly kill the germs, viruses, and pathogens you’re fighting.
A common mistake is to apply a disinfectant, then quickly wipe it away without letting the product rest on the surface. Since dwell times can vary between 30 seconds and 15 minutes, it’s important to let the disinfectant stay on a surface long enough to work its magic.
Dwell times aren’t a suggestion, they are a mandatory part of the disinfection process. According to preliminary studies, the Omicron variant of COVID-19 can last twice as long on surfaces as the original strain. This re-emphasizes the importance of practicing good hand washing, proper building ventilation, and applying the correct dwell time on high-touch surfaces such as door handles, handrails, and elevator buttons.
Your professional cleaning provider should train their technicians in the proper application of each disinfecting product for maximum effectiveness. Mister Kleen ensures that our technicians receive advanced training on the proper cleaning, disinfecting, and sanitizing of surfaces.
Dwell time is part of the three-part pathogen removal process of cleaning, sanitizing and disinfecting that your cleaning provider will conduct.
Cleaning is a necessary first step to remove dirt, dust, or debris so that the sanitizers and disinfectants can be effective. Once appropriate cleaning has been completed, EPA-registered sanitizers can be applied in proper concentrations and for the correct dwell time to further reduce the number of bacteria and viruses present in the workspace. The next step is disinfecting which includes using EPA-registered products that target a particular virus and leaving it on surfaces for the appropriate dwell time.
Dwell time is just one of the many factors your cleaning provider should be able to manage, so that you can spend less time worrying about the health and safety of your staff and customers.
