No, you do not need to fully clean/sanitize the tableware. We will do the full cleaning. However, you do need to rinse the food service items so that they are rinsed/wiped free of food or debris prior to return—it is very hard on the tableware to have food remnants/sauces crusted on them. A $200 cleaning fee will be charged if items are not rinsed free of food/debris prior to return.
