1. empty your refrigerator of food, etc. 2. take warm, soapy solution and clean all of your glass jars, bottles, especially on the bottoms. 3. use a solution of vinegar and warm water and wipe down all of the inside of your refrigerator, including taking the vegetable/fruit bins out and washing them. 4. rinse everything well.
instead of vinegar, you could also try baking soda and water.
After refrigerator is clean, place a new, opened box of baking soda in the back of your refrigerator to absorb odors. Replace every month.
I have also used a mild solution of bleach and warm water to clean my refrigerator.
