What Is Warewashing?
Also called: ware washing, dishwashing operations
Warewashing is the commercial process of cleaning and sanitising the items a food operation serves and cooks with — dishes, glassware, flatware, utensils and cookware. It is done either by machine or in a three-compartment sink, and both methods must reach a defined sanitising standard, not merely look clean.
The two methods
Machine warewashing
- High-temperature machines sanitise with heat at the final rinse
- Low-temperature machines sanitise chemically, usually with chlorine
- Requires scraping and racking first, plus temperature and chemical checks each shift
- Deliming, curtain cleaning and spray-arm checks keep the machine at standard
Three-compartment sink
- Wash in detergent, rinse in clean water, sanitise in a chemical solution, then air dry
- Sanitiser concentration is verified with test strips, not by eye
- The default for pots, pans and any item the machine cannot take
- Required as a backup whenever the machine is down
Why the word exists
"Warewashing" is the term used in health codes, equipment specifications and hotel job descriptions, where "dishwashing" is imprecise: the process covers glassware, flatware and cookware as well as plates, and it names a station and a workflow rather than a single task.
The item categories are usually broken out as chinaware, glassware, flatware or silver, and cookware or smallwares. Each has its own racking, handling and storage rules — glassware racks separately, silver is often soaked, cookware goes to the pot sink.
Air dry, never towel dry
Sanitised items are air dried. Towel drying re-contaminates a surface that has just been sanitised, which is why health inspectors look for drying racks rather than cloths, and why stacking wet is also a finding.
Frequently asked questions
Covering the warewashing station
The dish station is the first position to fail a service when someone calls out, because everything downstream stops without clean ware. Most operators cover it with on-demand staff rather than pulling cooks off the line.
