I “learned” this in college, too. And then I did a bit more research and discovered that the dishwasher was very much capable of cleaning, but only if it had appropriate detergent or cleaning solution. But commercial dishwasher cleaning solution is nasty and highly basic, so apparently whoever was in charged decided students shouldn’t have access to cleaning solution. So we only had sanitizer, and the dishwasher only sanitized.
After a discussion with the facilities department, I got cleaning solution and its feed line, and the dishwasher magically started washing dishes!
One should still spray the food off first, but commercial dishwashers wash just fine.
- sneak 3y agoI worked in a commercial kitchen that had all 3 (wash, sterilize, rinse) of the fluids properly stocked. (In fact, they didn't own the dishwasher or fluids, but subscribed to a machine rental, maintenance, and refill contract, which was just "x loads for y dollars per month, rain or shine", to make costs predictable for the low margin small restaurant.) You still need to thoroughly clean the dishes before they go in, otherwise in 1-2 loads the filters are completely clogged. They are absolutely not designed for dishes to go in that have any residual food on them. In a residential setting if you're going to clean the dishes to that extent, you should just finish washing them, as it's basically the same amount of time for a household's amount of dishes. The only time a commercial dishwasher makes sense is if you need to do dozens of plates and cups and kilograms of silverware. Commercial dishwashers are a bad choice for residential use.
