After the coronavirus began to spread across the United States, many people became hyper-aware of what germs might be lurking around them. One of the most notoriously dirty items that we regularly use is money.

Many outlets and merchants requested consumers start using contactless payment methods to avoid cash interactions at the register. Since a bill’s lifespan can last for up to 15 years, there could be COVID-19 and who-knows-what-else sliding through your fingers.

It was enough of a concern that China’s banks began disinfecting bills and coins with heat and ultraviolet light during the height of the pandemic’s effects there. Other than that, you can also think about using Douglas Laboratories or Nordic Naturals to provide immune system support.

Since those options may not be available to you at home, here’s how you can disinfect your cash.

Soak It in a Soap Solution

The Bank of Thailand was the first to make this suggestion to consumers during the start of the coronavirus pandemic. You can disinfect currency by washing it in a dishwashing soap solution for a short period. Rinse it thoroughly before placing it in the sunshine to let it air dry. Don’t use bleach or boiling water as that could damage the cash.

Leave It In the Sun

Although you might not have a UV light to use at home, regular sunshine can disinfect the currency’s surface. You can set it in a protected area (not in the window) to let the sun’s natural rays create safer money. Anything with a UV filter may enhance sunlight’s warmth, but it won’t kill the virus.

Use a Spray Disinfectant

If you have concerns about COVID-19 on your cash, a simple spray disinfectant can potentially kill the virus. You’ll need to get the currency damp for it to be effective. Each product has specific instructions to follow, so leave it on the money until it has the chance to be safer to use again.

If you can’t disinfect your money, please remember to wash your hands. Use soap and water for 20+ seconds to achieve a cleaner result. Hand sanitizer with over 60% alcohol content is a suitable substitute for handwashing, but not for disinfecting currency.
