Watch out for your kitchen sponge! I read this little news blurb on my iPhone today when I was waiting for a meeting to start at work, and it turns out that your kitchen sponge is the number one bacteria holder in your house. Ew! And to think that I put my bare hands on it on a daily basis... Shocking. Clearly, your sponge is something that is totally neglected, especially since it is not as gross as a toilet seat or other areas, but it is full of germs.
What you need to do to get your sponge in better order is number one, buy a new one! But if you don't want to do that, you can clean your sponge simply by soaking it in bleach or lemon juice. However, these are not the best methods, so the very best way to get rid of these germs is to put your sponge in the microwave, and then in the dishwasher. This is pretty interesting because I never thought of this method to clean a sponge, but it will work to kill all the germs at an extremely high heat. Now you can safely clean your kitchen once again! You're welcome.
