Why Proper Freezer Storage Matters

Storing a freezer isn't as simple as unplugging it and moving it to the garage or a storage unit. Improper storage can lead to issues such as:

Mold and mildew buildup
Electrical and mechanical problems
Damage from pests or moisture
Unpleasant odors that linger for months

Taking the time to store your freezer properly will save you money, prevent unnecessary repairs, and ensure it's ready for immediate use when needed.

Step-by-Step Guide: Preparing Your Freezer for Storage

1. Empty the Freezer Completely

Before storing a freezer, remove all food items. Even non-perishables or long-lasting foods should not be left inside. Food can spoil, create unpleasant smells, and even attract pests. Make plans to use up, donate, or dispose of everything inside.

2. Unplug and Defrost

Unplug the appliance at least 24-48 hours before you plan to move or store it. This allows ample time for the freezer to defrost completely. Here's how to handle this process:

Leave the door open to allow ice and frost to melt away.
Place towels or a container around the base to soak up water from melting ice.
Wipe down all surfaces with a clean, dry cloth once defrosting is complete.

3. Clean and Sanitize the Interior

It's imperative to deep clean your freezer before storage to prevent mold, mildew, and unwanted odors:

Use a mixture of warm water and mild soap to wipe down all interior surfaces.
Stubborn stains or odors can be addressed with a solution of 1 tablespoon of baking soda per quart of water.
Remove and wash all drawers, shelves, and removable compartments separately and let them dry thoroughly.

Tip: Leave the interior door open for a few hours after cleaning to ensure that it's completely dry before you proceed. Moisture is the most common cause of mold growth in stored freezers.

4. Address the Exterior

Wipe down the outside of the freezer with a damp cloth. Check for any damage or rust, and address it as necessary. If your freezer is stainless steel, use a polish to protect the finish.

5. Secure and Protect Power Cord

Wrap the power cord neatly and secure it with a twist tie or zip tie.
Tape it to the back or side of the freezer to prevent tripping or damage during storage and transport.
Ensure the prongs are covered to guard against moisture or corrosion.

How to Store the Freezer Properly

1. Store with the Door Ajar

One of the most important tips on how to store a chest freezer or upright freezer is to keep the door slightly open. This prevents the build-up of stale odors, moisture, mold, and mildew. Use a small wedge, towel, or purpose-built appliance door prop to keep the freezer door ajar by at least an inch.

2. Select the Right Storage Location

Choosing where to store your freezer can impact its longevity:

Climate-controlled storage facilities are best for long-term storage, as extreme temperatures can damage internal components.
Never store outdoors or in damp locations such as basements prone to flooding, as moisture can ruin your appliance.
If using a garage, place your freezer away from windows and sources of direct sunlight to prevent excess heat.

Tip: If you must store your freezer in a non-climate-controlled environment, cover it with a breathable cloth or appliance cover--never plastic, which can trap moisture and encourage rust.

3. Position Properly

Keep your freezer upright; laying it on its side can cause compressor oil to move into cooling lines, which may damage the appliance.
Ensure at least 2-3 inches of clearance around all sides for air circulation and prevent dust buildup.
If moving is required and it ends up on its side, allow the freezer to stand upright for 24 hours before plugging it back in.

4. Cover and Protect Your Appliance

To shield your freezer from dust and dirt:

Use a clean sheet or furniture cover (avoid plastic wrap).
Ensure the cover allows for air flow to avoid trapping moisture inside the unit.
For added protection in a busy storage area, surround your freezer with soft materials or foam pads to guard against accidental bumps and scratches.

Checking Your Freezer While in Storage

1. Regular Inspections

Even when your freezer is plugged in during storage, occasional checks are important. If unplugged, open it monthly to:

Ensure the door is still ajar
Check for moisture build-up, mold, or mildew
Look for signs of pests or rodent activity
Ensure no unpleasant odors are developing

2. Preventing Pests

Pests love to nest in warm, enclosed spaces. Place a few dryer sheets or cotton balls soaked in peppermint oil inside the freezer (and remove them before reuse) to act as a natural deterrent.

3. Absorbing Odors

Consider placing an open box of baking soda or activated charcoal inside the empty freezer throughout the storage period to absorb any lingering odors and keep your freezer smelling fresh.

How to Prepare Your Freezer for Use After Storage

1. Inspect Thoroughly

Before plugging in and reusing your stored freezer:

Check the interior and exterior for signs of mold or mildew.
Ensure the power cord and plug aren't frayed or damaged.
Remove any odor absorbers such as baking soda or charcoal.

2. Clean Again If Necessary

If you notice any dust or musty smells, repeat the cleaning process using warm, soapy water or a baking soda solution. Rinse and dry thoroughly before plugging in.

3. Let It Stand Upright

If your freezer was transported on its side, let it stand upright for 24 hours before plugging it in. This gives the refrigerant and compressor oil time to redistribute correctly, which helps prevent potential motor damage.

4. Test Before Full Use

Plug in the freezer and let it run empty for 4-6 hours or until it reaches the desired temperature.
Monitor for any unusual noises, leaks, or electrical issues.
Once running smoothly, reload with food items as needed.

Frequently Asked Questions About Freezer Storage

Can you store a freezer in a cold garage?

Yes, you can store a freezer in a garage, but it's best if the garage is dry and not exposed to temperature extremes. If the temperature drops too low, some freezers may not operate properly, and excess humidity can cause rust or mildew. Cover your freezer with a breathable material and keep the door ajar for optimal protection.

Should a freezer be unplugged during storage?

If you won't need the freezer for several weeks or months, unplugging is recommended to save energy. But, for long-term storage, ensure the interior is fully defrosted and dry, and leave the door slightly open to prevent mold and odor development.

How long can a freezer sit unused?

A properly cleaned and stored freezer can sit unused for many months, even up to one year or more, as long as it's protected from moisture, pests, and extremes of temperature.

What should I avoid when storing a freezer?

Don't cover with plastic - traps moisture inside, leading to mold and rust.
Never leave the door closed - creates a breeding ground for mildew, especially if any moisture remains inside.
Don't store outdoors - exposes your freezer to weather and animal damage.
Don't neglect pest prevention - insects and rodents can damage wiring and insulation.
