Hello everyone, I work in a beverage industry, making and packing Kombucha. We installed a new can packing line. For food safety prospective, do we need to clean the cans before filling them with beverages. We receive the cans covered from the supplier and we feed them to the filling line on a conveyer that is covered from the top to avoid any contamination. Please advise if we need to wash or rinse the cans before filling. Thanks
