Anyone who knows me, knows I am a nut about my kitchen being clean including my sponge. In professional kitchens you are required to sanitize all washed dishes. There are several ways of doing this depending upon if you are handwashing or machine washing. At the shop, since I couldn’t install a machine washer, we used bleach in the rinse water which is an approved method of sanitizing dishes, pots and pans. I have seen (but not tried) putting sponges in a microwave, dishwasher and outside in the sun. But one of the easiest, least expensive and most effective methods of not only cleaning but sanitizing is to add bleach to the water.
Kitchen sponges can not only get dirty
but can be the most unsanitary thing in the kitchen. I realized I was chucking these out with great speed. So I went back to my pro days and decided to clean and sanitize in one fell swoop.
Put a tablespoon of bleach in a bowl of warm water. Place the sponge in the water
and weight it down with another bowl.
Fill the top bowl with water to keep the sponge under the bleach water.
Let it sit overnight. Take it out in the morning and rinse it.
That’s it! Fresh, clean and ready to use it again.













Wow now that’s a clean sponge. I’d agree sponges and sink brushes have to be the dirtiest things ever. Great tip!
Thanks Vicki – I wondered about even posting this, but in the end decided it was worthwhile.
