Which of the following would you expect if you let surfaces stay wet for 5 minutes instead of 10 minutes? A A smaller percentage of the microbes would be killed. B Time does not play a role in how successful a disinfectant treatment is, so a 5 minute application will kill the same percent of the total population as a 10 minute application. C The germicide would remove just as many total microbes; 10 minutes is definitely more time than is necessary.
