Your garage is a versatile space—home to cars, tools, and seasonal decorations. But while it may seem like an ideal storage solution, not everything belongs in this environment. Temperature fluctuations, humidity, and potential pest infestations can damage certain items, making them unsafe or ineffective over time. Here are 10 things you should never store in your garage and why keeping them elsewhere is a better idea.
1. Paint & Other Chemicals
Why Not? Temperature extremes can cause paint to separate, dry out, or become unusable. Similarly, chemicals like pesticides and household cleaners can degrade, posing health risks.
Better Storage: Keep paint and chemicals in a temperature-controlled environment, such as a basement or utility closet.
2. Propane Tanks & Flammable Liquids
Why Not? Propane tanks are highly flammable and can leak or explode under high heat. Gasoline, oil, and other combustible substances also pose a fire hazard.
Better Storage: Store propane tanks outside, in a well-ventilated area, away from direct sunlight.
3. Paper Documents & Books
Why Not? Garages are prone to humidity and pests, which can lead to mold growth, paper degradation, and insect infestations. For more on pest infestations, we recommend this post: How To Deal with Pest Infestation in the Garage
Better Storage: Keep important paperwork, books, and photographs inside a climate-controlled room or a moisture-proof storage container.
4. Wooden Furniture & Fabric Items
Why Not? Wood can expand and contract with temperature fluctuations, causing warping and cracking. Fabric items like clothing, blankets, or upholstered furniture can attract moths, rodents, and mildew.

Better Storage: If you must store furniture, keep it in a dry, insulated room covered with breathable fabric.
5. Electronics & Batteries
Why Not? Cold temperatures can drain batteries, while excessive heat can damage wiring and circuitry inside electronics. Humidity can also cause corrosion over time.
Better Storage: Store electronics in a temperature-controlled environment, ideally indoors with low moisture levels.
6. Food (Including Pet Food)
Why Not? Storing food in your garage can attract rodents and insects, leading to contamination. Extreme heat and cold can also cause food to spoil faster.
Better Storage: Keep food in a pantry or kitchen cabinet, sealed in airtight containers to prevent pest invasions.
7. Wine & Other Perishable Liquids
Why Not? Wine and beverages degrade when exposed to fluctuating temperatures. Heat causes premature aging, while excessive cold can affect taste and consistency.
Better Storage: Wine is best kept in a cool, stable environment, such as a wine fridge or cellar.
8. Important Tools (If Unprotected)
Why Not? While garages house many tools, high humidity can cause metal to rust. Improper storage can lead to damage and safety risks when using compromised tools.
Better Storage: Hang tools on pegboards or keep them in sealed toolboxes with silica gel packs to absorb moisture.
9. Firewood
Why Not? Storing firewood in your garage can lead to pest infestations, including termites, ants, and rodents.
Better Storage: Keep firewood outside, covered but well-ventilated, at least 20 feet from your home.
10. Old Appliances & Refrigerators
Why Not? Unused refrigerators can become mold-prone, while older appliances often waste energy if plugged in unnecessarily.
Better Storage: Donate, recycle, or store appliances in a proper indoor storage unit if you plan to use them later.
