Spring Cleaning Your Sub-Zero Refrigerator


Sub-Zero refrigerators are designed for efficient operation and low maintenance. They are excellent at food preservation, but no refrigerator or appliance stays reliable without regular maintenance. A spring cleaning will keep your fridge running like new. Here are some steps you should take to maintain your appliance and ensure your kitchen is fully functional, food doesnโ€™t get spoiled, and excess wear doesnโ€™t damage the motor and other important parts.

Clean the Outside

All outside surfaces can be cleaned with soap and water (which can also kill the coronavirus). Or, you can use any non-abrasive liquid household cleaner. If the exterior is stained, apply baking soda, rinse it clean, and use a soft cloth to dry it. Stainless steel cleaners can be used when applicable but avoid using a lot to avoid streaking.

Clean Under and Behind the Refrigerator

Move your refrigerator away from the wall, raising the leveling legs to roll the fridge on its wheels. With the unit repositioned:

  • Sweep the floor underneath the appliance.
  • Clean the wall behind the refrigerator.
  • Clean the rear coils with a brush or vacuum.

Clean the Drip Pan

Unplug the fridge and remove the drip pan. Empty any water down a drain. Next, mix 1 part bleach, which can also kill the coronavirus, (or white vinegar โ€“ no evidence, yet, that it is effective against coronavirus) and 2 parts warm water in a spray bottle. Spray the drip pan and let it sit for a few minutes, then scrub away mold or buildup, rinse with warm water, and dry before replacing it.

Efficient Placement of the Air Circulation

Proper placement of food items improves airflow and puts less strain on the motor, as it wonโ€™t run as frequently. At the same time, this allows a more constant temperature throughout the appliance, including the freezer.

Dispose of Outdated Food

You should check the contents of your fridge at regular intervals. Throw away any old leftovers, and if odors are coming from any foods, get rid of them to clear the smell. And, never taste something to be certain. Itโ€™s best and safe to throw it out.

Check the Tightly Seal Food

Properly sealed foods will retain their flavors. This will also prevent the taste and odor of one food from transferring to another. Separating foods helps avoid this problem as well. The humidity-controlled compartments and adjustable shelving of a Sub-Zero are designed to separate food and prevent taste transfer.

Check the Temperature

Always keep your refrigerator at the manualโ€™s recommended temperature level. If it is too high, food is more likely to spoil faster. Lower than recommended temperatures are bad for produce. Either scenario will cause the motor to work harder.

Wipe Up Spills

Any spill in the refrigerator compartment should be wiped up immediately. Avoid using abrasives or harsh chemicals. If a spill has already dried, mix baking soda and water to soften it until it can be wiped up. Interior walls should be cleaned with a detergent, that just so happens to also kill the coronavirus, and a soft, lint-free cloth. Shelving can be cleaned with a glass cleaner.

Check and Replace the Water Filter

The water filter should be replaced if your fridge has a water dispenser. If thereโ€™s an air filter, replace that as well, and swap out filters for crispers that help keep fruits and vegetables fresh.
