Cleaning & Maintenance of Sub-Zero Wine Storage Units

If you are a wine lover, you probably know how important it is to store your wine collection properly. Wine is a delicate product that can be affected by many factors, such as temperature, humidity, light, and vibration. That’s why you need a reliable and high-quality wine storage unit that can protect your wine from these enemies and preserve its flavor, aroma, and quality.

One of the best options for wine storage is Sub-Zero, a brand that has been producing premium appliances for over 70 years. Sub-Zero wine storage units are more than just coolers; they are guardians against heat, humidity, vibration, and light. They also offer features such as dual temperature zones, full-extension wine racks, UV-resistant glass doors, inventory tile system, and Wi-Fi enabled controls.

But even the best wine storage units need some care and maintenance to keep them in optimal condition and ensure their longevity. In this article, we will give you some tips on how to clean and maintain your Sub-Zero wine storage unit, so you can enjoy your wine collection for years to come.

How to Clean Your Sub-Zero Wine Storage Unit

Cleaning your Sub-Zero wine storage unit is not a difficult task, but it requires some attention and regularity. Here are the steps you should follow:

  • Turn off the power to the unit at the control panel or the circuit breaker before cleaning.
  • Remove all the bottles from the unit and store them in a cool and dark place.
  • Remove the wine racks by pulling them out to full extension (or three-quarter extension for model UW-24), tilting them up, then lifting them up and out.
  • Wash the interior surfaces and all removable parts with a mild solution of soap, water, and baking soda. Rinse and dry thoroughly.
  • Avoid getting water on the lights, control panel, and cherrywood facing on the wine racks2.
  • Use a standard glass cleaner to clean the UV-resistant glass door.
  • Use a soft brush or vacuum cleaner to remove any dust or lint from the condenser grille at the bottom of the unit. If the service indicator light is on, it means that the condenser needs to be cleaned.
  • Wipe the exterior of the unit with a soft cloth dampened with mild detergent and water. Dry with a soft cloth.
  • Replace the wine racks by inserting them into the slides, tilting them down, then pushing them in until they lock in place.
  • Replace the bottles in the unit according to your preference. You can use the inventory tile system to label and organize your collection.
  • Turn on the power to the unit at the control panel or the circuit breaker after cleaning.

How Often Should You Clean Your Sub-Zero Wine Storage Unit

The frequency of cleaning your Sub-Zero wine storage unit depends on how often you use it and how dusty or humid your environment is. As a general rule, you should clean your unit at least once every six months. However, if you notice any signs of dirt, dust, mold, or odor in your unit, you should clean it as soon as possible.

How to Maintain Your Sub-Zero Wine Storage Unit

Besides cleaning your Sub-Zero wine storage unit regularly, there are some other things you can do to maintain its performance and efficiency. Here are some tips:

  • Check the temperature and humidity settings of your unit periodically and adjust them according to your needs. The ideal temperature range for wine storage is between 45°F and 65°F (and 55°F is often cited as close to perfect), though this isn’t an exact science. The ideal humidity level is around 70%, which helps prevent corks from drying out or rotting. You can use the electronic controls on your unit to set the temperature and humidity for each zone independently.
  • Avoid exposing your unit to direct sunlight or heat sources, such as ovens, stoves, radiators, or fireplaces. These can cause temperature fluctuations and damage your wine.
  • Avoid placing your unit near sources of vibration, such as speakers, washing machines, or generators. Vibration can disturb the sediment in your wine and affect its quality.
  • Keep your unit away from strong odors or chemicals, such as paint, solvents, or cleaning products. These can seep into your wine through the corks and alter its taste.
  • Do not overfill or underfill your unit. Overfilling can prevent proper air circulation and cause uneven cooling. Underfilling can make your unit work harder than necessary and waste energy.
  • Do not open or close your unit’s door too frequently or for too long. This can cause temperature and humidity changes and affect your wine’s condition.
