What Should and Should Not Go in a Storage Unit

Renting a storage unit is one of those things that feels straightforward until you are standing in front of it with a truck full of stuff. Most items store just fine, but a few common mistakes can lead to damage, odors, or unnecessary hassle later.


Knowing what belongs in a storage unit and what does not helps protect your belongings and keeps the experience simple.


Using a clean, well-maintained facility like All American Self Storage helps keep stored belongings protected and easy to manage over time.


Items that store well in a storage unit


Storage units are designed for everyday belongings that need a safe, dry place to sit for a while. Most household and business items fall into this category, as long as they are clean and packed properly.


Items that typically store well include:

• Furniture like sofas, tables, bed frames, and dressers
• Boxes of clothing, shoes, and accessories
• Seasonal decorations and household items
• Business inventory, paperwork, and office equipment
• Tools, sports gear, and garage items

Furniture and boxed household goods are some of the most common items people store, especially during moves, downsizing, or renovations.


Proper packing makes a big difference. Cleaning items first, using sturdy boxes, and labeling clearly helps prevent issues when you come back months later.


If you are using storage to sort through belongings long term, this guide on what you should keep and toss from storage is a helpful companion read.


Items that need extra care before storing


Some belongings can be stored safely, but they need a bit more attention because they react to temperature, humidity, or long periods without use.


These items include:

• Wooden furniture
• Electronics and televisions
• Books, photos, and documents
• Mattresses and upholstered furniture
• Musical instruments


For these items, preparation matters. Make sure everything is clean and completely dry. Wrap furniture to protect surfaces. Use plastic bins or moisture absorbers for sensitive items. Elevating belongings slightly off the floor can also help protect against moisture over time.


Items you should never put in a storage unit


Not everything belongs in storage. Most facilities prohibit certain items for safety and sanitation reasons, and for good reason.


Items that should never be stored include:

• Food or pet food
• Perishable goods
• Live plants or animals
• Gasoline, propane, or fuel containers
• Fireworks, ammunition, or explosives
• Paints, chemicals, or hazardous materials


Food and flammable materials cause the most problems. Even sealed food can attract pests or leak over time. Hazardous materials create safety risks for everyone on the property.


Before moving items in, double check boxes and coolers for forgotten liquids or food.


Seasonal items are ideal for storage


One of the most practical uses for a storage unit is rotating seasonal belongings. Items that take up space at home but are only used part of the year store especially well.


Common seasonal items people store include:

• Winter clothing and boots
• Holiday decorations
• Heaters and seasonal appliances
• Snow gear and cold-weather equipment


Storing these items during the off season keeps closets and garages usable year-round. This article on winter items you can store in a storage unit during the summer goes into more detail on how seasonal storage can free up space at home.


Why food and liquids cause the biggest problems


Food and liquids are responsible for many storage issues. It often starts small. A bag of snacks. A case of bottled drinks. A cooler that was not fully dried.


Over time, these items can leak, spoil, or attract pests. Odors spread quickly in enclosed spaces, and damage can extend beyond a single box.

Before locking up your unit, check for:


• Open containers
• Liquids hidden in bins or coolers
• Cleaning products that could leak
• Trash bags mixed in with stored items


Catching these early prevents bigger problems later.


Common storage mistakes to avoid


Even with the right items, poor packing can cause issues.


Some common mistakes include:

• Using weak boxes that collapse
• Storing items directly on the floor
• Packing too tightly with no airflow
• Forgetting to label boxes
• Blocking access to the back of the unit


Leaving a small walkway inside the unit makes it easier to reach items and spot issues early. It also saves time when you need something later.


Final thoughts


A storage unit works best when it is used for the right items and packed with care. Most household and seasonal belongings store safely when kept clean, dry, and organized. Items involving food, fuel, or hazardous materials should always stay out of storage.


A little planning upfront keeps your belongings protected and makes storage a helpful solution instead of a source of stress.

When summer rolls around, it is time to swap snow boots for flip flops, snowblowers for lawnmowers, and bulky jackets for breezy tees. The problem is not the transition. It is everything you are left holding once winter is over. Garages fill up fast, closets overflow, and basements become a maze of bins and gear you will not touch for months. Seasonal storage solves that problem cleanly. Storing winter items during the summer frees up usable space at home and helps protect gear you spent good money on. Below is a practical breakdown of why it works, what to store, and how to do it without creating a mess for future you. Why Store Winter Items During the Summer Most winter gear is bulky, awkwardly shaped, and completely unused for half the year. Leaving it out creates clutter and increases the chance of damage. Storing winter items in a storage unit during summer helps you: Free up garage and closet space for bikes, lawn equipment, and patio furniture Protect expensive gear from heat, moisture, and pests commonly found in garages and sheds Stay organized year round by rotating seasonal items instead of stacking them endlessly If you are unsure which items are still worth keeping long term, this guide on what you should keep and toss from storage can help you decide before moving everything into a unit. Winter Items That Are Ideal for Summer Storage Not everything belongs in a storage unit, but winter gear is usually a great fit. Here are the most common items people store once the weather warms up. Snow Equipment and Tools Snowblowers Snow shovels and ice scrapers Salt spreaders Before storing, clean everything thoroughly and drain fuel from powered equipment. Winter Sports Gear Skis and snowboards Sleds and snow tubes Snowshoes and helmets Keep sharp edges covered and store items off the floor when possible. Cold Weather Clothing Heavy coats and parkas Snow pants Boots, hats, scarves, and gloves Use labeled plastic bins or wardrobe boxes to keep items clean and easy to find later. Holiday Decorations String lights Inflatable decorations Seasonal signage and décor Pack decorations carefully to avoid tangled wires and crushed pieces. Tires and Vehicle Accessories Snow tires Tire chains Winter emergency kits Store tires properly to avoid warping and keep them out of direct sunlight. Heating Items and Miscellaneous Gear Space heaters Electric blankets Insulated pet shelters Firewood racks If it only comes out when temperatures drop, it probably belongs in storage during summer. If you are unsure whether something is allowed in a unit, this breakdown of what should and should not go in a storage unit is worth checking before packing. Tips for Storing Winter Items Safely Good storage is not about stuffing everything into a unit and closing the door. A little prep goes a long way. Clean and dry all items before storing to prevent rust, mildew, and odors Use plastic bins with lids instead of cardboard for better protection Label containers clearly so items are easy to find later Use wardrobe boxes for bulky coats and specialty clothing Store tires flat or on racks to preserve their shape If space is tight, it can help to reassess what you truly need to keep. This guide on what to keep and toss from storage is useful for avoiding long term clutter.
