Begin by laying a towel on the floor on front of the refrigerator.
Next, clear as many kitchen surfaces as possible.
Now, fill (1) side of your kitchen sink or a bucket with hot water and 1/4 cup of disinfectant. (In place of a bucket you can use your refrigerator drawers since you will be washing them during this process anyway)
Begin removing everything from the refrigerator or freezer and placing them on your cleared counters. This includes shelves and drawers.
Use the hot water to wipe the bottom of any sticky jars or containers as you replace food items.
Now you have clean refrigerator or freezer.
