Why Does My Garage Smell Like Gas?

Sources of Gasoline Odors in Your Garage

Bad odors kill the vibe, whether you’re trying to sell your home, impress guests, or simply live comfortably. Not only are gas fumes bad for your health, but if your garage smells like gas, it can make it very difficult to spend much time there.

Fortunately, you can usually narrow down the source of the gas smell to a few potential options. Here’s how Jerry tackled the issue:

Automobiles

Most homeowners use their garages primarily for vehicle storage. Garages keep your cars warm, dry, and safe. However, vehicles powered by gasoline are often the main source of gas odors. Here’s how Jerry checked his car:

Inspect the Gas Tank and Fuel Line: Jerry started by inspecting his vintage Mustang. The gas tank is generally underneath the trunk. He didn’t need to hire a mechanic to inspect the undercarriage. He examined the tank and the pipe that runs up to the gas cap, running his hand over the area to feel for dampness. If anything was damp, there was a good chance of a gas leak.

Smell Test: He also used the smell test. The closer he got to the vehicle, the stronger the gasoline smell. This was another clear sign that the automobile might be leaking gasoline.

Professional Help: Luckily, Jerry didn’t find any leaks. But if you suspect a gas leak, take the vehicle in for an inspection. Hiring a professional to fix the problem is wise since you’re dealing with a flammable substance.

Home and Garden Equipment

Storing equipment and appliances such as lawnmowers and trimmers in the garage makes perfect sense. However, these items can also be a source of gasoline odors. Here’s how Jerry handled his equipment:

Inspect for Leaks: After checking his Mustang, Jerry inspected his lawn equipment. He found that his lawnmower’s carburetor was slightly wet with gasoline. Jerry took his lawnmower to a professional repair shop, where they confirmed a small leak and repaired it.

Clean and Test: Jerry also checked his trimmer, which hangs on the wall. It turned out that some gasoline had leaked from the carburetor. He cleaned the equipment thoroughly and left it outside overnight. The next day, the odor in the garage had significantly improved, confirming the source of the smell.

Gas Containers

Gas containers often have vents to allow fast pouring, but if these vents are left open, they can release gasoline fumes. Here’s Jerry’s experience:

Close Vents: Jerry realized that one of his gas cans had its vent open, likely contributing to the smell. He replaced the faulty gas container with a new, tightly sealed one and made a note to always check the vents after use.

Removing Gasoline Smell from Your Garage

Even after addressing the source of the smell, it might take some time for the odor to completely disappear. Here are effective methods Jerry used to eliminate lingering gasoline odors:

Cat Litter

Cat litter is highly effective at absorbing gasoline spills:

Application: Jerry poured cat litter over the spill and let it sit for several hours.

Cleanup: Then he swept up the litter and disposed of it safely, following local guidelines.

Baking Soda

Baking soda can neutralize odors:

Create a Paste: Jerry mixed baking soda with warm water to create a paste.

Apply and Clean: He applied it to the affected area, let it dry, and then swept it away.

Dish Detergent

Grease-cutting dish detergent helps break down gasoline residues:

Scrub: Jerry mixed detergent with water and scrubbed the area.

Rinse and Dry: Then he rinsed thoroughly and dried with rags.

Pine-Scented Disinfectant

A pine-scented disinfectant can mask and neutralize odors:

Apply and Scrub: Jerry mixed it with water, applied it to the smelly area, scrubbed, and dried.

Temporary Scent: The strong pine scent eventually faded, taking the gasoline odor with it.

Improving Garage Ventilation

Good ventilation is crucial for preventing and eliminating gasoline odors:

Air Circulation: Jerry opened his garage doors in La Grange, IL and windows to allow fresh air to circulate. He also used fans to enhance airflow.

Ventilation System: He installed an exhaust fan to improve ventilation, which made a significant difference.

Preventing Future Garage Odors

To keep your garage smelling fresh, follow these tips:

1. Avoid Running Machinery: Avoid running machinery in the garage.
2. Close Doors: Always close the door between the garage door and your home.
3. Store Safely: Store chemicals and gasoline in sealed containers.
4. Seal and Finish: Finish and seal your garage floors and walls to prevent absorption of fumes.
5. Safety First: Install a carbon monoxide detector for safety.
