Old sponges are gross -- but here’s why you shouldn’t throw them out
Sponges are meant to be cleaning products, but they can’t quite do their job when they’re crawling with bacteria—which yours probably is. We’ve already talked about why kitchen sponges are the germiest place in your house, but here’s a little refresher: Sponges are ideal for cleaning because they’re so good at holding water. The downside is, that makes them warm and moist—the perfect environment for bacteria to thrive.
Worst of all, there’s really no good way clean out all that bacteria out once it’s cozied up in your sponge’s pores. A recent study in Scientific Reports found no cleaning method could get rid of more than 60 percent of bacteria. (Don’t miss these other 11 items you should be cleaning way more often.) To keep your cleaning tools, well, clean, the authors recommend swapping out for a new sponge once a week—way more than most people throw theirs out. Buying replacement sponges all the time seems like a waste of money, so what’s a thrifty homeowner to do?
Turns out, you don’t need to ditch an old sponge for good once you’ve banished it from the kitchen.
First things first: Get as much bacteria out as you can by using the only way microbiologists approve cleaning a sponge.
