If you enjoy hand-washing dishes about as much as catching the subway in 90° heat, there's now a scientific reason to ditch the chore. According to Huffington Post, rinsing plates before putting them in the dishwasher or simply cleaning dishes by hand is absolutely pointless.
Here's why: Bacteria dies when exposed to extremely high temperatures. A normal dishwasher cycle can reach 140° to 145° Fahrenheit, but our skin can't handle scorching hot water. In other words, that tepid pool of filth you dip a dish into rinses the surface grime away, but bacteria remains intact.
If you're still not convinced, there's also the issue of your kitchen sponge. Dr. Philip Tierno, a clinical professor at the microbiology and pathology departments at NYU Langone and author of The Secret Life of Germs, says your kitchen sponge is the single dirtiest thing in your house. "It has a lot of nooks and crannies, so as you clean up a mess with potential pathogens in it, some of the organisms become lodged in between the sponge," he told Huffington Post.
Yes, the message is loud and clear: Step away from that dirty dishcloth and invest in a dishwasher stat.
