I am a home banker. I shut down. I am getting ready to reopen. Just need ideas.

Just give a very through cleaning to the kitchen including washing down the walls.  Be sure to clean all door knobs, handles etc  maybe call your health dept to see what they recommend 

The virus cannot be transferred to food. That’s the latest evidence. It’s the most important to clean all the surfaces where you will be decorating in a mild bleach solution. Including all utensils. Wash your hands frequently, wear a hairnet. If you do all this, you will be perfectly safe. If you and your family have been self isolating, with minimal contacts, you should be ok.
