Half a lemon stored in your fridge will help control and eliminate unpleasant smells.
Turn the temperature control off then unplug your fridge.
For stuck on interior stains, you can sprinkle a little baking soda directly on the spot and add just a little water to it to make a paste. Allow this to set on the stain and then scrub gently and allow the paste to remove the gunk.
When cleaning out your fridge, always use baking soda and warm water to wipe the insides of your refrigerator and freezers- soap or dishwashing liquid will leave a smell and can taint food.
Scuffs and stains can be removed by rubbing with non-abrasive tooth-paste, while grease spills will succumb to a little lemon juice and water.
