Here’s what you need to know about what will and won’t work against coronavirus, according to experts. - NBCNewsBETTER
It’s easy to go online and find advice about how to make your own hand sanitizer. So, is this a good idea? Opinions vary. The World Health Organization and Consumer Reports advises against it.
“Most of the experts that we've talked to have said this is not the best idea,” Roberts said. “You may not get the concentrations right. And if your solution doesn't have a high enough concentration of alcohol, it won't be doing you any good.” Sachleben also has concerns about DIY hand sanitizer recipes. He’s a chemist and even he said he doesn’t mix his own disinfectant products at home. “You’ll never know what you’re doing is as good as what you can buy at the store,” he said. “If you buy it, you know it'll work.”
Swartzberg believes that doing something is ultimately better than doing nothing, but he worries that DIY hand sanitizers might give people a false sense of security. “I’m concerned people will not prepare it with the correct percentage of alcohol,” he said. “People may be fooling themselves into thinking that they’re using something that will help, when it won’t.”
Remember: Alcohol-based hand sanitizers are not as effective when our hands are visibly dirty or greasy. That's why it's important to wash with soap and water.
