So my refrigerator sat for 8 days without power. I threw out a bunch of rotting food

2. Here's what I found online

Wipe the inside of the fridge or freezer with equal parts vinegar and water. Vinegar provides acid, which destroys mildew.
Leave the door open and allow the refrigerator to air out for several days.
Stuff both the refrigerator and freezer with rolled newspapers. Close the door and leave for several days. Remove the paper and clean the interior with vinegar and water.
Sprinkle fresh coffee grounds or baking soda loosely in a large, shallow container in the bottom of the refrigerator and freezer.
Place a cotton swab soaked with vanilla inside the refrigerator and freezer. Close the door for 24 hours. Check for odors.
Use a commercial product available at hardware and housewares stores. Follow the manufacturer's instructions.
