Garage storage can be incredibly versatile, but not all items are suited for this environment. Understanding what shouldn’t be stored in your garage is key to maintaining a safe and efficient space.
In this post, we’ll explore three critical factors that influence what items are best kept out of your garage. By the end, you’ll have a clearer idea of how to make smarter storage choices.
Let’s delve into these factors and understand why certain items simply don’t thrive in a garage setting.

Are The Items Temperature Dependent?
Wine
Wine, for example, doesn’t fare well in a hot, humid garage. If wine is stored in fluctuating conditions for too long, it can spoil.
This happens when the wine oxidizes, meaning the heat and moisture cause the cork to loosen, letting air in and contaminating the wine. One night in a garage won’t ruin wine, but five months might.
Beer
Paint
Wood Furniture

Are Any Of The Items Considered Hazardous?
Propane Tanks
People often keep extra propane tanks in garages without considering safety guidelines. Propane is highly flammable and doesn’t handle heat well. In winter, you can store propane tanks outside on plywood or concrete, away from the house.
In summer, keep them in a shaded, ventilated area, or in a detached garage, away from electrical or flammable items. For more on propane storage, visit Amerigas.com.

Cleaning Products
Most cleaning products can be stored in a garage if safety measures are followed. Always read the label for storage instructions. Products like bleach and ammonia should be kept in a separate storage unit within the garage to maintain the correct temperature.

Final Thoughts
Considering the above factors when storing items in your garage will prevent you from making common garage storage errors. If you’re considering, for example, storing the spare bottle of wine in your garage, think about how temperature may impact the overall quality of the wine.
Additionally, reconsider storing hazardous materials in alternative locations, aside from your garage. Finally, locate alternative locations when storing items that may attract vermin.
