15 things you should never store in your garage

Garages are convenient storage spaces, but not everything belongs there. Heat, humidity, and pests can damage certain items quickly, even in a seemingly secure space. Knowing what not to store can save you time, money, and headaches later.

This list highlights 15 things you should never store in your garage. Avoiding these items helps keep your belongings safe, your garage organized, and your home worry-free.

Paint and Solvents

Extreme temperatures can ruin paint, causing it to separate or dry out. Solvents can also become unstable or even flammable when stored in hot garages. Keep these chemicals in a climate-controlled area instead.

Electronics

Heat and moisture damage electronic components over time. Computers, TVs, and gaming consoles may malfunction if left in a garage. Store them indoors in a dry, cool environment to protect their lifespan.

Prescription Medications

Fluctuating temperatures can reduce the effectiveness of medications. Many prescriptions require consistent, moderate temperatures. Keep them inside your home where conditions are stable.

Photographs and Important Documents

Paper products are highly sensitive to humidity and heat. Photographs, passports, and certificates can warp or fade. Store these items in a cool, dry, and secure place inside the house.

Liquids Like Cooking Oils

High heat can cause oils to spoil or go rancid quickly. Some oils may even leak or expand in containers. Keep them in the pantry or another controlled area.

Food Items

Rodents, insects, and extreme temperatures make garages unsafe for food storage. Even canned goods can swell or spoil in heat. Always store edible items indoors in sealed containers.

Aerosol Cans

Heat can increase pressure in aerosol cans, risking leaks or explosions. This includes household cleaners, spray paint, and bug repellents. Store them in a cooler, ventilated area to prevent accidents.

Tires

Rubber tires can crack and degrade when exposed to direct sunlight or fluctuating temperatures. Long-term storage in a hot garage reduces their lifespan. If you must store them, keep them in a cool, dry spot out of sunlight.

Gasoline and Other Flammable Liquids

Extreme heat can make gasoline highly volatile. Improper storage can lead to dangerous fires. Keep fuels in approved containers away from your home, ideally in a ventilated shed.

Musical Instruments

Wood and metal instruments are highly sensitive to temperature and humidity changes. Heat and moisture can warp, crack, or rust instruments. Always store them indoors with controlled climate conditions.

Leather Items

Leather cracks and dries out in hot or fluctuating conditions. Jackets, bags, and furniture left in garages lose flexibility and shine. Keep leather indoors to maintain its longevity.

Antiques and Collectibles

Valuables like ceramics, figurines, or old books are vulnerable to temperature swings. Moisture and heat accelerate deterioration. Store antiques in a controlled environment to preserve their condition.

Wine

Heat rapidly ages and spoils wine, even if bottles are sealed. Wine should be stored in a cool, dark space with consistent temperatures. Avoid the garage unless it is climate-controlled.

Artwork

Paintings, prints, and sculptures are highly sensitive to temperature and humidity. Improper storage can cause warping, cracking, or fading. Protect your art by keeping it indoors in stable conditions.

Batteries

Heat accelerates battery degradation and increases the risk of leakage. This includes car batteries, rechargeable batteries, and small household batteries. Store them indoors to maximize performance and safety.

Your garage is a handy storage space, but some items simply don’t fare well in fluctuating temperatures or humidity. Avoid these 15 things to keep your belongings safe, functional, and long-lasting.
