Cleaning the deep freezer maintains a safe food environment and fresh smell. More importantly it improves the efficiency of the freezer. The time to complete the job depends on size and amount of food transferred during cleaning. No special cleaning fluids are needed, just regular household items.
Follow the manufacturer's manual for additional procedures and to see if your deep freezer needs defrosting before cleaning.
Turn electrical controls off and unplug the freezer.
Remove any frozen foods into an ice cooler or refrigerator freezer.
Allow any inside ice buildup to thaw and remove excess water from the bottom. Use towels to absorb the water and wring them out in a bucket.
Use a washcloth to wash the inside and trays with dishwashing liquid and water. Use a bucket to mix the solution. Scrub away bits of food and grime stuck on the lid, trays and along the seal well.
Add 2 tbsp. of baking soda to 1 qt. warm water for a final wash down.
Wipe dry the interior and trays.
