Act quickly to soak up the gas, then use a cleaning solution to break down the residue and eliminate the odor. The key is immediate action to prevent the gasoline from soaking through the carpet and damaging the underlying padding, which can lead to persistent fumes and a potential fire hazard.
Start by ventilating the area. Open all the car doors and windows. Put on gloves and safety glasses. Gasoline is highly flammable and its vapors are harmful, so never attempt this in an enclosed space like a garage.
Your first step is to absorb as much liquid as possible.
- Dry Absorbents: Liberally cover the stain with an absorbent material like cat litter, baking soda, or a commercial oil-absorbent product. Let it sit for 15-20 minutes to draw the gas out of the carpet fibers, then vacuum it up thoroughly.
- Wet/Dry Vacuum: If you have access to a wet/dry vacuum, this is highly effective. Use it to extract the gasoline without any cleaning solutions first.
After absorbing the bulk of the spill, you need to clean the stain. Avoid harsh chemicals that might set the stain or damage the carpet. A simple mixture of dish soap (like Dawn) and water is very effective at cutting through the oily residue. Apply the soapy solution with a brush, blot with towels, and rinse with a cloth dampened with clean water. Blot dry.
For lingering odors, a final treatment is crucial. Sprinkle baking soda over the area and let it sit for several hours or overnight before vacuuming. As a stronger alternative, a commercial enzymatic cleaner designed for pet stains can neutralize the odor-causing compounds effectively.
