University of Florida researchers say a microwave can do more than just heat your food.
It can also zap the germs out of your sponges.
Researchers soaked a sponge in raw wastewater, filled with fecal bacteria.
They nuked the sponge in a household microwave and claim it killed all of the bacteria, viruses, and parasites.
After just two minutes 99% were dead.
It took up to 10 minutes to zap "all" of the bacterial spores.
One extra note, researchers say your microwave must be on full power to get the best results, and for safety reasons, your sponges must be wet.
