Speaking of sponges, there have been many discussions online about the germs found in sponges and what will work to clean them. The New York Times published an article that quoted a study from Germany claiming that cleaning a sponge only makes the bacteria on them worse. But after further research, the author wrote another article that said cleaning your sponge is still important to do. So the debate seems to remain up in the air.
However, if you still want to clean your sponge, you can either put it in the microwave on high for a minute or try a tool called a SpongeBath that uses citric acid to keep the sponge clean and disinfected.
