Reusable shopping bags should be washed or cleaned after every use during the Covid-19 pandemic, according to Reader’s Digest. But don’t worry, it’s not that difficult. Bacteria, yeast, mold and viruses can attach themselves to your grocery bag so if you are immunocompromised or feel vulnerable, you’ll be safer using one-use disposable bags. Most fabric bags are made of cotton or bamboo. Launder cotton bags in hot water with your regular laundry load. Bamboo bags need the gentle cycle. Air dry or machine dry both. Nylon or plastic should be hand-washed in warm soapy water, air-dried after. Insulated reusable bags need surfaces washed with mild soap and water, followed by a thorough antibacterial wipe and air dry.
