According to the USDA, the top method for eliminating bacteria in a sponge is microwaving it or placing it in the dishwasher.

To kill bacteria in the microwave, remove any handles or hard pieces from the sponge. Then wet the sponge and microwave it for 60 seconds. Allow it to cool for a few seconds before removing it.
