It is safest to not reuse any that were used to store meats. But to clean and dry them for reuse, it is easiest to turn them inside out. To run them through a dishwasher inside out, place them upside down over supports or utensils and clip the bottom with office or clothes clips to avoid finding them in the bottom of your dishwasher. To avoid heat damage to bags and save on electricity, do not use the hot air dryer portion of timer and instead roll out the racks to air dry immediately when rinse cycle is finished.
