Just like our glasses and dishes, we need to clean the clean mechanism. Do you really want to use a sponge for cleaning the flatware that was used to wipe up a spill on the floor. NO. Remember that its important to maintain the freshness and cleanliness of these items. Couple of suggestions:
1. Place the sponge in the dishwasher and run with a regular load.
2. If you don’t have a dishwasher, try wetting the sponge and placing in the microwave for 45 seconds. *Caution the sponge will be hot*
