Many of us use a plastic sponge in the shower when using body wash, but we never think: Do we need to clean something that helps us get squeaky clean? Those nylon mesh sponges can be a breeding ground for bacteria over time, so follow these steps to keep them clean: Every eight weeks or so, toss them into your washing machine and launder them with white clothes or sheets anytime you decide to use chlorine bleach. The bleach will disinfect them. Remove from the washer and air dry. Good as new!
