Michael Petruccelli says; Use a vacume cleaner to clean behind & underneath the refrigerator at least once a year. Clean & dust the sides and top of your refrigerator also. Check & clean the interior shelves, lining and door gasket every three months. Help the inside of the refrigerator smelling clean by keeping a cup of baking soda in the refrigerator at all times. A slice of lemon or lime will also work.
