WebMD says: Your microwave may be a powerful weapon in protecting your family against disease-causing germs.

A new study shows zapping sponges and plastic scrubbing pads in the microwave can kill bacteria, such as E. coli, that can cause illness.

“Basically, what we find is that we could knock out most bacteria in two minutes,” says researcher Gabriel Bitton, professor of environmental engineering at the University of Florida, in a news release. “People often put their sponges and scrubbers in the dishwasher, but if they really want to decontaminate them and not just clean them, they should use the microwave.”

Researchers say disease-causing bacteria and germs from uncooked eggs, meat, and vegetables often work their way onto countertops and cleaning tools, and the dampness of sponges, dish cloths, and scrubbers provide an ideal breeding ground for the bugs.
