Empty the dishwasher of all dishes, utensils, cookware and glasses.
Pour one cup of white vinegar into a dishwasher-safe cup. Place the cup on the top rack of the GE Profile.
Pour one cup of baking soda into the bottom of the dishwasher, if desired. This increases the cleaning power of the vinegar and helps freshen the appliance.
Close the GE Profile door and run the appliance through the heavy-duty cycle. When the cycle is completed, the dishwasher can be loaded with dirty dishes.
