Cleaning Your Kitchen Sponge Won't Make It Clean

For many people washing your kitchen sink sponge is a good way to get some extra uses out of it before replacing it. But cleaning it apparently does nothing to rid it of all the germs hidden inside its porous surface.  A recent study found that regularly cleaned sponges, such as those zapped in the microwave, placed in the dishwasher or soaked in boiling water, were no cleaner than sponges simply left to fester in their own dirt. Researchers found that kitchen sponges were filled with a class of bacteria that are potential carriers of dreadful germs that can lead to food poisoning, cholera, and even the plague!  Plus they can cross- contaminate as you use the sponge to wipe down the counter and then wash dishes. Sponges can harbor bacteria fairly well because of their porous structure and although a cleaned sponge is cleaner than one never rinsed, it can be hazardous to your health!  The best way to keep this germy threat to a minimum is to regularly replace kitchen sponges every week.
