Pro tips for effectively storing an unused freezer

Posted on 18/06/2025

If you have recently upgraded your home appliances, downsized your living space, or simply have a freezer that you won't be using for a while, it's essential to know how to store it properly. Correctly storing an unused freezer can prevent mold, mildew, foul odors, and electrical issues when you're ready to use it again. Whether it's a chest freezer, upright freezer, or a small compact freezer, follow these expert tips for storing your unused freezer and ensure its longevity and functionality.

1. Why Proper Storage of a Freezer Matters

Many homeowners underestimate the importance of safely storing an unused appliance. Freezers are significant investments, and improper storage can lead to maintenance headaches and higher costs in the future. Issues such as mold growth, unpleasant odors, and mechanical malfunction are all common pitfalls when an unused freezer isn't taken care of. By following the right steps, you can extend your freezer's lifecycle and retain its performance for years to come.

Key reasons to store an unused freezer correctly:

• Prevent mold, mildew, and bacteria from growing inside.
• Avoid rust and electrical damage due to improper placement or moisture exposure.
• Maintain gasket integrity, preventing expensive repairs.
• Simplify setup when it's time to use the freezer again.

2. Preparing Your Freezer for Storage

A freezer requires thorough preparation before being put into storage, whether in a garage, basement, storage unit, or shed. Here are the most effective ways to prepare an unused freezer for storage.

A. Switch Off and Unplug

Begin by turning off the freezer and unplugging it from the power outlet. Never store a freezer while it's still running or plugged in, as this can cause safety hazards and energy waste.

B. Remove All Contents and Shelves

• Take out all food items, ice, and freezer packs from the appliance.
• Remove detachable shelves, drawers, and baskets. Wash them with warm soapy water, dry them thoroughly, and store them separately if possible or inside the freezer with the door ajar.

C. Defrost Thoroughly

A crucial pro tip for storing a freezer is to completely defrost the freezer. This prevents residual ice from melting and causing water damage or mold growth.

• Leave the freezer door open after unplugging and allow all ice and frost to melt.
• Use towels to soak up any excess water.
• Check for and remove residual water in drain trays or pans located underneath the unit.

D. Deep Clean the Interior

Once dry, clean the entire inside of the freezer:

• Mix a gentle cleaning solution of baking soda and water or vinegar and water.
• Wipe down all surfaces with a clean cloth, including walls, ceiling, floor, and compartments.
• Clean the door gasket (the rubber seal) to remove crumbs or sticky residues that may attract pests or degrade the material.

E. Ensure the Freezer Is Dry

Leave the freezer door open for several hours, preferably overnight, in a well-ventilated area to be certain all moisture has evaporated. Moisture is a top culprit for mold and mildew inside stored appliances.

3. Selecting the Right Storage Location

Choosing an appropriate storage spot is crucial for keeping your freezer in optimal condition. Here are some top recommendations for placing your unused freezer:

• Pick a dry location. Basements, garages, or climate-controlled storage units are ideal.
• Keep out of direct sunlight to avoid heat damage and fading.
• Avoid damp, humid places where condensation could form and cause rust or mildew.
• If storing in a garage or shed, elevate the freezer off the ground with pallets or blocks to minimize moisture exposure and protect against small floods.

Storage temperature guidance:

• Indoor storage units: Always better for temperature consistency.
• Outdoor sheds/garages: Use only if there's no risk of freezing or excessive heat.

4. Properly Positioning Your Freezer for Storage

For long-term storage of a freezer, position matters. Here's what you should keep in mind:

• Store the freezer upright. Laying a freezer on its side or back can cause compressor oil to flow into undesirable places, potentially damaging the appliance when turned upright again.
• Leave the door ajar. This is vital: keep the freezer door or lid slightly open (use a rolled-up towel or a purpose-built appliance wedge) to:
  • Enable air circulation
  • Prevent musty or moldy odors
  • Discourage mildew and bacteria growth
• Secure the power cord: Coil and bind the electrical cord neatly, securing it to the back of the freezer using twist-ties or tape. This prevents tripping hazards and accidental damage to the plug or wiring.
• Allow clearance around the appliance. Place the freezer at least a few inches away from walls or other objects to promote airflow and avoid condensation buildup.

5. Protecting the Freezer's Exterior and Components

An unused freezer in storage is vulnerable to dust, pests, and accidental scratches. Take these protective measures:

Cleaning and Covering

• Wipe the outside with a damp cloth plus mild detergent.
• Polish with a stainless-steel-friendly cleaner if applicable.
• Cover the appliance with a breathable cloth sheet or purpose-made appliance cover.
• Avoid plastic tarps or films that trap moisture and can cause rust.

Pest Prevention

Placing a few sachets of baking soda or a bowl of activated charcoal inside can absorb odors and moisture. Some users also leave a dryer sheet to deter insects and rodents. Ensure no food crumbs are left behind to avoid attracting pests.

Pad or Block Feet

If the freezer will be moved again, pad its feet with foam or cardboard to protect floors and prevent skidding.

6. Long-Term Storage Considerations

Storage Duration

If you expect to store your freezer unused for more than a few months, check it periodically for dust, pests, or moisture buildup. Every few months:

• Open the door/lid to inspect the interior.
• Replace baking soda, charcoal, or dryer sheets as needed.
• If possible, wipe down surfaces to ensure freshness.

Cord and Component Integrity

Every 6-12 months, inspect the electrical cord, plug, and gasket. If any show signs of damage, address repairs before plugging the freezer back in.

7. Avoiding Common Mistakes When Storing a Freezer

Let's highlight some typical errors that can shorten your unused freezer's lifespan:

• Not cleaning out food residue, leading to pests or persistent odors
• Leaving the door tightly closed; lack of airflow encourages mold and mildew
• Storing in humid, unventilated places that cause rust or electrical issues
• Laying the freezer on its side or back rather than upright
• Using non-breathable plastic wraps that trap moisture

8. Bringing Your Freezer Out of Storage

When you're ready to return your unused freezer to service, here's what you should do for a smooth reactivation:

1. Inspect the freezer inside and out for dust, pests, rust, and mold.
2. Use a damp cloth to clean the interior and exterior again.
3. Check the gasket for flexibility and cleanliness.
4. Examine the electrical plug and cord for damage or fraying.
5. For chest and upright freezers, let the appliance stand upright for at least 24 hours before plugging in (particularly if it's been moved horizontally).
6. Plug in and run empty for a few hours, then load with food once cold.

9. Frequently Asked Questions About Storing Freezers

How long can I store an unused freezer?

A properly prepped and positioned freezer can be stored unused for years. However, periodic inspections and cleaning at least twice a year are recommended.

Can I store my freezer outdoors?

It's best to store freezers indoors. If you must use a shed or garage, ensure the location is dry, weatherproof, and safe from freezing temperatures and direct sunlight. Never store outside unprotected.

Should I use any chemicals inside my stored freezer?

Avoid chemical cleaners or pest repellents inside the freezer. Rely on natural absorbers such as baking soda and periodically clean for maximum freshness.

What's the best way to leave the door ajar?

Insert a towel, purpose-made wedge, or special appliance spacer between the door and seal. This provides enough airflow without exposing the interior excessively.

Conclusion: Maximize Your Freezer's Lifespan with Proper Storage

An unused freezer doesn't need to become a liability. Proactively caring for your stored freezer can save money, effort, and time in the long run. By diligently cleaning, defrosting, drying, and positioning your freezer, you can ensure it remains in working condition whenever you need it again. Remember, these pro tips for effectively storing an unused freezer not only protect your investment but also provide peace of mind. Keep this guide handy as a checklist, and your unused freezer will be ready for reactivation at a moment's notice!
