Take a mixture of one part baking soda and seven parts water in a spray bottle, spray the mixture on the interior and wipe with a clean cloth. Rinse off with clean water.
Get rid of odor
Mix vinegar and baking soda and wipe the insides of your refrigerator. Rinse with water and leave a little baking soda powder in an open container to absorb bad odor in the future.
Clean the doors
You don't need special cleaners for this. Just wipe the doors with a wet microfiber cloth and then with a completely dry one. If water isn't enough, clean with a few drops of alcohol.
Under the refrigerator
Unplug the refrigerator and use a vacuum cleaner to clean the surface under your fridge thoroughly. Do this once every three months.
Clean the handles and sides
Everyone at home touches the refrigerator's handle, so it can gather germs. Use a regular liquid cleanser and a soft cloth to clean the handle and sides of the fridge.
