After regular use (sandwiches, snacks, fruits, veggies, non-food items, etc.), your ZipFresh bags can go straight in the dishwasher. However, for prep-meal or food items, it is recommended to rinse the inside of your ZipFresh bag with hot water to loosen and wash out any remaining food debris. Depending on the food items, additional soaking and/or disinfecting may be needed. Note: Do not turn your ZipFresh bag inside out to reduce the chances of damaging the internal produce-saver film.Avoid trapping moisture by drying and/or storing your ZipFresh bags with the seals open.
