<human>:  What is the most efficient way to clean the fridge?
<bot>: The most efficient way to clean the fridge is to start by removing everything from the shelves. Wipe down the shelves and walls with a mild disinfectant or all-purpose cleaner. Throw away any expired food or food that has gone bad. Put the remaining food back in an organized fashion, and wipe down the door handle and any other external surfaces. Finally, use an old rag soaked in vinegar to give the fridge an extra clean.
