A refrigerator can become a dangerous breeding ground for bacteria that can make the food you store inside unhealthy very quickly. Twice a year, make it a priority to clean the inside of your fridge and freezer, and purge any food items that are past their expiration date. Wash the interior of the fridge with a solution of warm water and baking soda to loosen hard spills so they can be wiped out. If it's possible, pull the fridge out from the wall and vacuum underneath and behind it, since dust buildup can force a fridge to work harder.
