As temperatures drop across Missouri, it’s important to think carefully about what you’re keeping in storage—especially during the winter months. While a storage unit is an excellent solution for decluttering or protecting your belongings, not everything handles the cold well. Some items can warp, crack, or spoil when exposed to low temperatures and fluctuating humidity. To help protect your valuables, here’s a list of things you should avoid keeping in long-term storage during the winter.
Cold weather can wreak havoc on electronics. Items like TVs, computers, cameras, and speakers contain delicate components that can expand and contract when temperatures fluctuate. This can lead to cracked screens, damaged circuits, and even corrosion from condensation. If you must store electronics, choose a climate-controlled storage unit that maintains a stable temperature year-round. According to Consumer Reports, extreme cold can shorten battery life and cause permanent damage to devices if not properly protected.
Any liquid that can freeze should never be stored in non-climate-controlled units during winter in Missouri. Paints, cleaning products, and beverages can expand as they freeze, causing containers to burst or leak. Even if they don’t explode, temperature changes can alter their consistency and render them useless. Instead, store these items in a temperature-stable environment like a basement or garage that stays above freezing.
Wood and leather are particularly sensitive to cold and moisture. When exposed to freezing temperatures, wood can shrink, crack, and warp, while leather can dry out and lose its natural oils. Over time, this leads to permanent damage that’s expensive to repair. If you plan to put furniture in long-term storage, consider wrapping it with breathable covers and, ideally, storing it in a climate-controlled unit. For more protection tips, visit The Spruce.
Musical instruments—especially those made of wood, such as guitars, violins, and pianos—do not handle winter conditions well. Cold and humidity changes can cause tuning issues, cracking, and even joint separation. Brass and string instruments are also vulnerable to corrosion if condensation forms. Always store instruments indoors where both temperature and humidity are consistent.
Perishable food should never be placed in storage, no matter the season, but especially not in winter. Freezing temperatures can cause spoilage, while even sealed containers might attract pests once they thaw. Similarly, plants can’t survive the lack of sunlight and freezing temperatures found in most storage units. If you’re relocating or traveling, make alternative arrangements for living plants and consumables.
Items like candles, lotions, and cosmetics can be sensitive to temperature fluctuations. Candles may crack or lose shape in the cold, while beauty products can separate or expire faster. These items should be kept in a temperature-controlled space to maintain their quality.
Knowing what not to store can save you time, money, and frustration. Protect your belongings from winter damage by choosing the right type of storage and carefully preparing your items before locking them away.
