It’s always interesting when you go to someone’s house for dinner and then offer to help clean up. People are rarely in agreement on how and where items go in the dishwasher. Some people arrange silverware face up, while others insist forks, spoons, and knives should always go in face down. I wondered which was the best way of loading my cutlery to ensure that they come out sparkling and clean, so I asked an expert. Her advice was surprising.
