How to Disinfect Sponges

Quickly heating up your sponge in the microwave can kill bacteria, including E. coli, and refresh it for longer use. Just make sure the sponge is damp and free of any cleaners before you pop it in the microwave. A dry sponge can catch fire, while heating up a sponge that has been soaked in soap or other industrial cleaners could cause it to emit unhealthy fumes.

Instead, soak your dirty kitchen sponges in water and a small amount of lemon juice or vinegar, both of which have anti-bacterial properties. Microwave them for up to two minutes on full power (the heat does the killing). The bonus is that the steam from the wet sponge will actually clean your microwave, too.
