23 Things You Should Never Keep in Your Garage

Storing items in the garage is a common practice for many homeowners, but not everything belongs in this often unpredictable environment. Temperature fluctuations, moisture, and pests can damage certain belongings or even pose safety hazards. To help you keep your items in good condition and your home safe, here are some things that should never be stored in the garage.

Propane Tanks

Propane tanks are highly flammable and can pose a significant safety hazard if stored in the garage. The temperature fluctuations can cause the tank to expand and contract, increasing the risk of a leak. A small spark, static electricity, or even a minor collision can ignite the propane, leading to an explosion. It’s best to store propane tanks outside in a well-ventilated area, away from any potential sources of ignition.

Pet Food

Storing pet food in the garage can attract pests such as rodents, insects, and even larger animals. The fluctuating temperatures can also cause the food to spoil or lose its nutritional value. Pet food is best kept indoors in a sealed container to maintain its freshness and prevent any unwanted visitors from feasting on it.

Paint

Wine should be stored in a stable, cool environment with consistent humidity. The fluctuating temperatures in a garage can spoil the wine by causing it to age prematurely or develop off-flavors. Additionally, exposure to light can degrade the quality of the wine. Store wine in a dedicated wine cellar or a climate-controlled area inside your home to maintain its quality.

Carpeting

While it might seem convenient, a refrigerator in the garage can struggle to maintain the correct temperature due to the lack of climate control. In hot weather, it has to work harder to stay cool, increasing energy consumption. In cold weather, it may not work efficiently, leading to food spoilage. It’s better to place your refrigerator in a climate-controlled area.

Wood

Oily rags are a significant fire hazard when stored in the garage. They can spontaneously combust due to the heat generated by the oxidation process of the oils. This can lead to a dangerous fire that can quickly spread. It’s crucial to store oily rags in a metal container with a tight-fitting lid, away from any flammable materials, or dispose of them properly.

Sleeping Bags
