Cleaning Products That Destroy Coronavirus
Soap and Water
Just the friction from scrubbing with soap and water can break the coronavirus’s protective envelope. “Scrub like you’ve got sticky stuff on the surface and you really need to get it off,” says Richard Sachleben, an organic chemist and member of the American Chemical Society. Discard the towel or leave it in a bowl of soapy water for a while to destroy any virus particles that may have survived.
Bleach
The Centers for Disease Control and Prevention recommends a diluted bleach solution (â…“ cup bleach per 1 gallon of water or 4 teaspoons bleach per 1 quart of water) for virus disinfection. Wear gloves while using bleach, and never mix it with amonia or anything, in fact, except water. (The only exception is when doing laundry with detergent.)
“Bleach works great against viruses,” Sachleben says. Just don’t keep the solution for longer than a few days because bleach will degrade certain plastic containers.
Bleach can also corrode metal over time, so Sachleben recommends that people not get into the habit of cleaning their faucets and stainless steel products with it. Because bleach is harsh for many countertops as well, you should rinse surfaces with water after disinfecting to prevent discoloration or damage to the surface.
Isopropyl Alcohol
Alcohol solutions with at least 70 percent alcohol are effective against coronavirus. Do not dilute the alcohol solution. Alcohol is generally safe for all surfaces but can discolor some plastics, Sachleben says.
Hydrogen Peroxide
According to the CDC, household (3 percent) hydrogen peroxide is effective in deactivating rhinovirus, the virus that causes the common cold, within 6 to 8 minutes of exposure. Rhinovirus is more difficult to destroy than coronaviruses, so hydrogen peroxide should be able to break down coronavirus in less time. Pour it undiluted into a spray bottle and spray it on the surface to be cleaned, but let it sit on the surface for several minutes.
Hydrogen peroxide is not corrosive, so it’s okay to use it on metal surfaces. But similar to bleach, it can discolor fabrics if you accidentally get in on your clothes. “It’s great for getting into hard-to-reach crevices,” Sachleben says. “You can pour it on the area and you don’t have to wipe it off because it essentially decomposes into oxygen and water.”
What Not to Use Against Coronavirus
Homemade Hand Sanitizer
You’re probably seeing all sorts of hand sanitizer recipes floating around your social media and the internet, but Thomas, at Upstate Medical in Syracuse, advises against making your own. “People don’t know the right ratios to use, and the internet won’t give you the right answer,” he warns. “Not only can you hurt yourself, but it could give you a false sense of security.”
Sachleben seconds that advice. “I’m a professional chemist, and I don’t mix my own disinfectant products at home,” he says. “Companies spend a bunch of time and money to pay chemists specifically to formulate hand sanitizers that work and that are safe. If you make it yourself, how can you know if it’s stable or if it works?”
Vodka
There are widely circulated recipes on the internet using vodka to combat coronavirus. A couple of vodka makers, including Tito’s and Smirnoff, have already come out with statements telling their customers that their 80-proof product does not contain enough ethyl alcohol (40 percent compared with the 70 percent required) to kill the coronavirus.
Distilled White Vinegar
Disinfection recommendations using vinegar are popular online, but there is no evidence that they are effective against coronavirus. (Read about the 9 things you should never clean with vinegar.)
