You wipe it off immediately
If you want to disinfect your house properly, you have to let it do its job on the surface for a few minutes, then wipe it down. If you are wondering how long does a disinfectant need to stay on a certain surface in order to kill germs, you should read the product label to make sure you are using it correctly.
According to Jennifer Walden, WikiLawn Lawn Care’s director of operations, if you wipe it off immediately, “you might catch some surface bacteria, but anything deeper will linger. Read the label and see how long you need to wait. Most chemical disinfectants take about 10 minutes to activate.”
“The longer you can let it be in contact, the better,” said Dr. Andrew Janowski, instructor of pediatric infectious diseases at Washington University School of Medicine St. Louis Children’s Hospital. “What I’ve been doing at home: I wait roughly a minute if I’m applying a spray product and then wiping.”
