You may feel tempted to store your dirty dishes in the handwashing sink, but it’s not the ideal place. The main reason is that when you work in the food service industry, you must have access to a handwashing sink at all times.
When you wash your hands, you need to do so for 10 to 15 seconds with soap and water to properly clean them.
If the sink is full of dirty dishes, there is the risk of cross-contamination and not cleaning your hands completely.
Not to mention, there’s no room for you to wash them.
So, to answer your question: Is It Okay To Use A Handwashing Sink To Store Dirty Dishes? Not really.
The dirty dishes should be stored in their proper location to avoid breaking any food regulation laws based on your location.
There should be at least a two to three-bay sink that you can place the dirty dishes.
However, the first bay usually has to be cleaned once every four hours, so every four hours you would have to empty it, clean, and sanitize it according to most regulations.
