You may think of your toilet as one of the dirtiest places in your home. Turns out, there’s at least one thing that’s worse: your kitchen sponge.
Researchers conducted a DNA analysis of 14 kitchen sponges and found more than 350 types of bacteria. Around a third of those weren’t harmful.
Even if you clean your sponge, you could still be spreading germs.
The team recommends replacing your sponge every week.
