Stinky, nasty, putrid
All words that come to mind when I pick up a kitchen sponge or washcloth that has gone bad. I swear, sometimes they seem to turn foul in a matter of minutes.
Not surprisingly, kitchen sponges are a happy home for a multitude of bacteria
You may have recently seen media reports about how many bacteria live in the typical kitchen sponge—the biggest collection of bacteria in the entire household, eek! The reporting at the time also indicated that cleaning your sponge in the dishwasher or microwave could cause more harm than good, but it turns out that may not be true. Whew.
All the same, it’s recommend that you change your sponge every few weeks
Sounds a bit wasteful to me, but I’ve found some sponges that don’t make me feel bad about this practice. My favorite are Twist sponges. They’re made of plant material and are biodegradable. I toss them in my compost after a few weeks.
