Experts Agree 'Deep Cleanings' Are Pretty Pointless for Most Situations During COVID-19


When the COVID-19 pandemic first hit, people scrambled to grab any kind of disinfectant they could get their hands on. Lysol and Clorox wipes became such a hot commodity that they started selling on Amazon for grossly inflated prices. Plenty of stores also started touting their cleanliness in ads, including Target, which has a sweet one about an ever-smiling manager mopping the outside entryway to her building at sunrise.

Now, it seems, all of that may have been for nothing. The Centers for Disease Control and Prevention (CDC) released a science brief earlier this week that states that the average person's risk of contracting COVID-19 from a surface is one in 10,000, or 0.01%. While the brief says that "it's possible" for people to be infected with COVID-19 from touching an infected surface and then touching their nose, mouth, or eyes, the organization also says that the "risk is generally considered to be low."

The CDC followed that up with new guidelines about cleaning your home, pointing out that regular household cleaners that contain soap and detergent are just fine for most people. (If you have someone in your home with a known COVID-19 infection, though, the CDC recommends using disinfectants.)

The takeaway? All of those intense cleanings amounted to what's being called "hygiene theater." This term is coming up a lot lately. Here's a breakdown of what it means, and why it can even be harmful.

What is hygiene theater, exactly?

Hygiene theater is a term used to describe the practice of taking hygiene measures to give off the feeling of improved safety without actually lowering risk of catching an illness—in this case, COVID-19. It refers to all of the stadiums, grocery stores, businesses, and even people in individual homes that have been doing intense cleaning since the pandemic began, even though there's been little proven benefit from those sometimes extreme measures.

The term first became popular in a July 2020 article published in The Atlantic. "What if this is all just a huge waste of time?" writer Derek Thompson mused. He later followed that up with a February 2021 article, stating that hygiene theater is "still a huge waste of time."

Doctors agree that deep cleanings are largely useless in combatting the pandemic.

"It's a waste of time," Richard Watkins, MD, an infectious disease specialist and a professor of internal medicine at the Northeast Ohio Medical University, tells Health. "People should focus their efforts on more productive endeavors.

Infectious disease expert Amesh A. Adalja, MD, senior scholar at the Johns Hopkins Center for Health Security, agrees. "It's stupid," he says. "People have been doing this from the very beginning and it's just theater."

The CDC says that it's "possible" to contract COVID-19 from touching an infected surface and then touching your mouth, nose, or eyes, but far from the main way people contract the virus—by breathing in infected droplets. Dr. Adalja stresses that the risk of getting from surfaces is very low. "I've never cleaned my mail or groceries," he says. "This doesn't do very much. People transmit COVID-19 through close contact."

This doesn't mean you should take a vacation from cleaning regularly, though. "Obviously, if someone sneezes on a table and they have COVID, you want to clean it," Dr. Adalja says. "But when someone goes to a podium after another person, and they've got people up there cleaning in between…that's just foolish."

What is the harm in hygiene theater?

While spending a lot of time cleaning on its own isn't necessarily harmful—and it can be necessary for those who have underlying health issues like a lowered immune system—Dr. Adalja is concerned about the message it sends. "It gives people the wrong impression about what is and isn't risky," he says.

It also gives people a "false sense of security, because people don't realize that's not the main way they could get infected," says Dr. Adalja. Take the example of wiping down groceries and mail with disinfecting wipes versus wearing a securely-fitted mask—the CDC clearly states that mask use is far more protective than cleaning those surfaces. But "if someone doesn't know better, they think it's what they should be doing instead," says Dr. Adalja.

OK, so how should you be cleaning?

The CDC has incredibly detailed information on this, both for when everyone in your home is healthy and for when someone with a known COVID-19 infection is in your house.

At baseline, the CDC recommends that you clean your home "regularly" with standard household cleaners, and specifically suggests the following:

  • Clean high-touch surfaces regularly and after you have visitors in your home.
  • Focus on high-touch surfaces such as doorknobs, tables, handles, light switches, and countertops.
  • Clean other surfaces in your home when they are visibly dirty or as needed.
  • Clean surfaces using a product suitable for each surface, following instructions on the product label.

If someone in your home is sick, the CDC suggests taking these steps to clean your place:

  • Always follow the directions on the label of your disinfectants. Many products recommend keeping the surface wet with a disinfectant for a certain period of time.
  • Clean visibly dirty surfaces with household cleaners containing soap or detergent before disinfecting if your disinfectant product does not have a cleaning agent.
  • Use a disinfectant product from the Environmental Protection Agency's List N of products that are effective against SARS-CoV-2, the virus that causes COVID-19.
  • Wear gloves for all tasks in the cleaning process.
  • Wash your hands often with soap and water for 20 seconds after you remove your gloves.

If you've been a fiend about cleaning during the pandemic, doctors say you can relax a bit. "I wouldn't stress it," Dr. Adalja says.
