Expert Interview – Warewashing, More than just Washing Dishes

An effective warewashing program can ensure kitchenware cleanliness, enhance guest satisfaction, and save money. For this edition of The Expert Interview, I spoke to my colleague Angel Rodriguez. As a Chemical Sales Manager at Imperial Dade, Angel oversees the Environmental Service Program in the Tri-State region. With over 16 years of experience in the industry, Angel has a wealth of knowledge on the topic.

LC: What exactly is warewashing?

AR: Warewashing is the term associated with cleaning and sanitizing any kitchenware used in the preparation, serving, or storing of food. This would include pots and pans, cutlery, glasses, serving pans, and trays. Warewashing can be done by machine or manually. This process is a key factor in ensuring that a commercial kitchen provides a clean and safe dining experience for their customers.

LC: You mentioned cleaning and sanitizing. Can you explain the difference?

AR: Great question! Cleaning removes food and other debris from the surface of an item, such as a plate. Sanitizing is the next step. Sanitizing kills the microorganisms and germs on the cleaned surface, making it safe for food contact.

LC: I think we all have an understanding of manual warewashing. It’s what we do at home, correct?

AR: Yes, but in a commercial environment there are specific steps and regulations. At home you may wash a plate with retail detergent, dry it, and put it away. In a restaurant you must wash the plate with a commercial-grade detergent, rinse, and then sanitize in water that contains 200 parts per million of sanitizer. That last step is the one that causes the most challenges. For example, if the water is too hot, the sanitizer will not be maintained at the appropriate level.

LC: And if that happens, is the sanitizing step compromised?

AR: Yes, and if a health inspector performs a test, it will result in a violation. It is really important to have a proper 3-compartment sink system, use the correct products and follow procedures.

LC: Does using a dish machine make the process easier for the operator?

AR: Commercial dish machines require less labor and, especially in large establishments, are much more efficient than manual washing. But there are still procedures and maintenance that need to be performed.

AR: First, the operator must consider the best type of machine. There are many sizes and configuration ranging from a small under-counter model, which would be appropriate in a bar area or small café, to a large conveyor model used in a hotel. These machines operate at high or low temperatures. Low temperature machines are less expensive and more energy efficient, but require more chemicals. There are trade-offs that need to be analyzed.  Every situation is unique. This is why it is important for operators to work with an experienced supplier, one that will take the time to determine the best system for their needs.

LC: Okay, once the correct equipment is chosen and installed, what are the steps to make sure the program runs smoothly.

AR: Scheduled preventative maintenance is crucial. A technician will change chemical lines, squeeze tubes, and dilution tips to make sure that the proper amount of detergent and chemicals are being used by the machine. These items can wear out, and if neglected can shut down the system. This can cause a major halt to a kitchen while waiting for an emergency service call.

AR: Using the right detergents and chemicals for the machine type is another important factor. The warewashing system components operate together so substituting or leaving out products will cause problems and can result in health code violations.

LC: Sounds like there is a lot more to a warewashing program than simply washing dishes.

AR: It is a very important process, however when set up and maintained correctly, it will free up kitchen staff and managers to focus on their menu and their guests’ satisfaction.

LC: Thanks, Angel!
