Dish sponges encounter moisture and food debris every day. This guide draws on food-safety education from the Academy of Nutrition and Dietetics to reduce cross-contamination. No household cleaning method should be assumed to make an old sponge sterile.

1. Reserve your dish sponge for dishes. Do not use that same sponge on raw-meat or poultry juices, floors or garbage bins.
2. Remove stuck food and thoroughly rinse away soap and debris under running water immediately after washing up. Wash your hands too.
3. Squeeze out as much water as possible and let the sponge dry in an open, ventilated holder. Do not leave it in pooled sink water or a closed, damp container.
4. Use disposable paper towels or a separate, appropriately laundered cloth for raw-meat spills and counters, then clean any contaminated work surfaces correctly.
5. A manufacturer-approved dishwasher drying cycle may reduce microbes on compatible sponges, but it does not guarantee sterilization. Avoid microwaving or harsh chemicals without product-specific safety guidance.
6. For frequently used sponges, assess replacement after roughly one to two weeks, earlier if smelly, damaged or heavily soiled. Let the replacement sponge dry between uses.
