The Best Way to Sanitize Kitchen Sponges


No one likes the idea of cleaning dishes with a germy sponge. But we've all heard about several methods for cleaning them. Which is best?

We worked with EMSL Analytical testing lab in Westmont, New Jersey, to find out. Consumers used sponges for a week in their kitchens, and the lab tainted others with three common pathogens: salmonella, E. coli, and pseudomonas.

We tested six cleaning methods to see which removed the most bacteria:

- Dishwasher
- Microwave
- Washing machine
- Bleach soak
- Ammonia soaks
- Vinegar soak


The Best Germ Killer

The bleach solution killed 99.9% of the three bacteria strains from all our test sponges (scrub and regular cellulose), a benchmark based on the EPA's requirement for sanitization of non-food-contact surfaces.

Here's how to do it:
Mix 3/4 cup of bleach in one gallon of water, and soak the sponge for five minutes.

Runners Up

The microwave and the dishwasher were the next most effective, zapping 99.9% of germs from the home-used sponges and from the lab-treated scrub sponges. However, on the lab-treated cellulose sponges, microwaving just missed the mark for E. coli (99.83% reduced), and the dishwasher didn't quite get all the salmonella or E. coli (99.88 and 99.86% reduced, respectively).
