How to Securely Store a Freezer That's Not in Use: The Complete Guide
A freezer is an essential household appliance, but there are times when you might need to store it for months or even years--maybe you're moving, downsizing, or just don't need it for the season. Knowing how to securely store a freezer that's not in use is crucial for maintaining its longevity, efficiency, and ensuring it's in top shape when you need it again. Improper storage can lead to mold, odors, pest infestations, or even permanent damage. This in-depth guide covers all steps and precautions for safe freezer storage, whether in a garage, self-storage unit, or elsewhere.
Why Properly Storing a Freezer Is Important
Many people underestimate the importance of preparing and storing a freezer safely when it's not in use. Poor storage practices can result in:
- Mold and mildew growth from lingering moisture or leftover food particles
- Pest infestations such as rodents and insects seeking shelter or food
- Unpleasant odors that can be difficult to remove
- Mechanical damage from improper positioning or environmental conditions
- Costly repairs or needing to buy a new freezer if damage is severe
Taking the proper steps to store your unused freezer will help it last longer and ensure a hassle-free experience when it's time to use it again.
Step-by-Step Guide: How to Securely Store a Freezer That's Not In Use
1. Unplug and Empty the Freezer
The first step in storing an unused freezer is to unplug it from the power source. Make sure to do this at least 24 hours before moving or cleaning, so the appliance can fully defrost.
- Remove all contents (food, ice trays, racks, baskets, and drawers)
- Defrost any ice build-up to prevent water leakage and mold during storage
*Tip*: If your freezer doesn't have an auto-defrost feature, place towels around the base to soak up water as ice melts.
2. Clean the Interior and Exterior Thoroughly
Sanitizing your appliance is crucial before long-term storage of a freezer.
- Mix a solution of warm water and mild dish soap or vinegar
- Wipe down all interior surfaces, shelves, baskets, and door seals
- Remove stubborn odors using a mixture of baking soda and water
- Rinse with clean water and dry thoroughly with a microfiber cloth
- Clean the exterior, especially the coils at the back, to prevent dust accumulation
Do not skip drying! Moisture is the enemy; any residual dampness can lead to mildew and musty smells.
3. Leave Doors Open to Prevent Mold & Odors
One of the best practices for securing a freezer for storage is to leave the door or lid slightly open. This air circulation wards off mustiness and stops mold from developing.
- Use a rolled-up towel or a special appliance spacer to keep the door ajar
- Never use a tight seal--lack of airflow can trap moisture and lead to mold
- Consider leaving a box of baking soda inside to absorb lingering odors
4. Secure All Removable Parts
Before moving your freezer to a storage area, ensure that all shelves, baskets, and racks are removed or secured. Loose parts can shift and cause damage during transport.
- Tape or fasten shelves and drawers with painter's tape or plastic wrap
- Label any removed parts and keep screws/small pieces in a bag attached to the freezer
5. Choose the Right Storage Location
Where you store your freezer matters!
- Select a dry, well-ventilated area to reduce the risk of condensation and corrosion
- If storing in a garage, basement, or shed, verify it's not prone to flooding or high humidity
- Outdoor storage is not recommended unless the freezer is specifically rated for it
- For long-term or off-site storage, opt for a reputable, climate-controlled self-storage facility
Avoid bright sunlight or exposure to weather, as UV and moisture can degrade plastic and seals over time.
6. Elevate and Cover the Freezer
Place the freezer on wooden pallets, bricks, or blocks to keep it off the ground. This protects from pests, accidental flooding, and aids ventilation.
- Use breathable covers like cotton or canvas to shield from dust while allowing air circulation
- Avoid plastic tarps, as they can trap moisture and promote mildew
7. Secure Cords and Door
Coil the power cord loosely and secure it to the back with a zip tie or hook. If you're worried about accidental closure or kids opening the door, use a bungee cord or child-lock device to keep the door slightly open and secure.
8. Protect From Pests
Mice and insects love dark, quiet places--don't let your freezer become their home!
- Place pest deterrents (such as cedar blocks or mothballs) nearby, but never inside the freezer
- Regularly check for droppings, nests, or damage to wiring and seals
9. Perform Periodic Checks
If you're storing the freezer for several months or more, set reminders to:
- Inspect the appliance every 2-3 months for leaks, rodents, or smells
- Wipe away any condensation that may have appeared
- Refresh odor absorbers such as baking soda or charcoal
10. Prepare for Reactivation
When you're ready to use the freezer again:
- Inspect for evidence of pests, mold, or damage
- Clean and dry once more
- Plug in and monitor to ensure it reaches the proper freezing temperature before refilling
For ultimate safety, refer to your manufacturer's manual for any model-specific storage recommendations.
Extra Tips For Safely Storing a Freezer That's Not in Use
- Store upright, not on its side, unless manufacturer guidelines allow this
- If storing for over a year, periodically lubricate the door gasket with petroleum jelly to prevent dry rot
- Label the freezer "Empty - In Storage" clearly, especially in shared spaces or storage units
- Keep the serial and model numbers handy in case you need replacement parts or service
Common Mistakes to Avoid When Storing an Unused Freezer
- Leaving moisture inside: This almost always leads to mildew
- Storing with food residue: Residual crumbs or spills can cause severe odors and attract pests
- Placing directly on a damp or concrete floor: Leads to rust and potential electrical hazards
- Airtight wrapping: Restricts airflow and traps humidity inside
- Forgetting to check periodically: Could lead to long-term damage and surprises upon reactivation
FAQ about How to Store a Freezer Securely While Not in Use
Should you store a freezer with the door or lid open or closed?
Always store the freezer with the door or lid slightly open, using a prop or spacer. This allows air to circulate, preventing mildew and stale odors.
Is it okay to put a freezer in a hot or freezing garage?
Extreme temperatures can wear out seals and gaskets, and may even crack internal components. Ideally, choose a climate-controlled environment, but if you must store the freezer in a garage, make sure it's well-insulated and protected from temperature extremes.
Can you lay a freezer on its side during storage?
Most manufacturers recommend storing upright. If you do lay it down for transport, allow it to stand upright for at least 24 hours before plugging in, so compressor oil can settle.
Is it necessary to secure the power cord?
Yes, keep the cord secure and out of walkways to prevent tripping hazards or rodent damage.
How do you remove smells before storage?
Try a deep clean with baking soda, followed by airing out for several hours. Place an open box of baking soda inside during storage to absorb any residual odors.
Conclusion: Secure Freezer Storage Preserves Value and Functionality
Learning how to securely store a freezer that's not in use is more than just unplugging it and putting it aside. With proper cleaning, drying, ventilation, pest prevention, and a smart storage location, your appliance will be protected against common hazards. Always remember to periodically check on the unit and follow these comprehensive best practices, so when it's time to freeze your next batch of groceries, your freezer will be ready for reliable performance.
