Dwell time is the amount of time a surface must remain in contact with the disinfectant applied, visibly wet surfaces or spaces sealed with fog, in order to do what it says it can do, I.e. kill pathogenic microorganisms before the disinfectant is wiped off or released.
If germs are not being killed then they can mutate and actively spread enabling infectious outbreaks to occur. This is a major factor that impacts the efficacy of disinfecting surfaces. Proper disinfectant procedures and dwell times must be used to prevent the spread of microorganisms and bacteria.
Did you know, the leading household spray requires 10 min to kill 99.9% of viruses and bacteria, while many mistakenly wipe it off after less than a minute.
