Gasoline has a pervasive odor that can make your car reek. In addition, it can make you light-headed, dizzy, or nauseated. The first thing to do is deal with a spill right after it happens, if you can, by getting rid of as much gasoline as possible. Then you should scrub the spill down. You can also try a variety of tricks to help lessen the odor. However, if you can't locate the source of the spill, you should have your car checked out by a mechanic, just in case you have a gas leak.

Let the gasoline evaporate. Once you've soaked up as much as you can, let the sun do the rest. Leave the car open in a sunny spot, so it will dry out the spot and draw the gasoline into the air. Try to leave it open for at least 4 to 5 hours.^{[5]

Cleaning the Spill

1
Make a cleaning solution. Create a simple solution of carpet shampoo and water. Use about 3 cups (720 milliliters) of tap water to 1/2 a cup (120 milliliters) of shampoo. Stir it gently until it is well combined.^{[6]

Scrub the mixture in. Using a nylon brush or a rag, apply the mixture to the spill. Scrub it in, applying more solution as you need it. Make sure to use a rag or brush that you don't mind throwing out.^{[9]

Eliminating the Smell

1
Rub in some coffee grounds. Some people have good luck using coffee grounds to eliminate gas smells. All you do is rub grounds into the affected area. After a week or so, vacuum up the coffee, and the smell should be lessened.^{[12]

- Some experts recommend trying a short coffee treatment before you shampoo the area.
2
Pour on the baking soda. Some people cover up the smell by dousing it in dry baking soda. They leave the baking soda on it all the time, switching it out monthly or so by vacuuming up the old and adding a fresh layer.
- You can also use baby powder instead of baking soda.
3
Add a layer of kitty litter. Another option is kitty litter, which is designed to absorb moisture and smells. Pour it on the spill, and leave it for at least a day before vacuuming it up. You may need to repeat the process several times.
4
Try an odor-eliminating spray. These sprays are designed for fabrics, so they may make a difference when it comes to a gasoline smell. Spray it on generously, and then allow it to air dry.^{[13]

- Try using an air freshener or odor spray that has antibacterial properties.^{[14]

The biggest thing people miss when trying to clean up foul smells is the cabin filter. Most modern cars have a cabin filter. Because of the way air conditioning works, the pathogens or bacterial elements that are making the car stink will also be in the cabin filter.
Question

Two to three gallons of gasoline spilled in the back of a RAV4 trunk area, onto the carpet. I've tried all of your suggestions and the smell has lessened, but is still pervasive. What else can I try?

Try baking soda with vinegar and a little warm water. If you park your car in a secure garage/inside, leave your doors open for as long as you can to let the smell evaporate.
