How to Deodorize a Car

Cars develop smell over time from food, pets, messes, and other sources. Luckily, a car is usually easy to deodorize in a few simple steps. Clean your car thoroughly and apply substances to remove odor. If you notice a potentially dangerous smell, like the smell of gas, seek professional assistance immediately. Most smells, however, can be dealt with without mechanics or professional cleaners.

If you notice an unpleasant smell in your car, search your car for a potential cause. Search the floor of your car for anything that could cause odor, like clothing, spills, or food. Be sure to search under seats, in between seats, any compartments or cup holders, and in the trunk.^{[1]XResearch source}
Get a large trash bag and toss any obvious causes of odor, such as food wrappings, old napkins, and anything else. Even things like magazines can cause a musty odor if they become damp. Removing any items from your car that don't need to be there can help cut down on odor. ^{[2]XTrustworthy SourceConsumer ReportsNonprofit organization dedicated to consumer advocacy and product testingGo to source}

Use a vacuum to clean your car's interior. Make sure to clean everywhere in your car, including under rugs and carpeting and under seats. Vacuum down the seats as well. Make sure to place the vacuum's nozzle into the nooks or crannies of seats so you can get any dirt and debris lodged in between seats.^{[3]XResearch source}
- You can use a handheld vacuum if you have one at home, but making a trip to a car wash is usually more effective. You can use the nozzle vacuum cleaner there, which should be able to thoroughly remove dirt and debris from your car that may be causing a bad smell.

Remove any spills and stains from the carpeting. If you notice any spills while you're cleaning, use a commercial carpet cleaner or a shampoo from a department store. Apply the cleaner to the floor according to package directions. Then, rub the cleaner into a stain with a soft cloth or sponge and then rinse the cleaner from the car with water.^{[4]XTrustworthy SourceConsumer ReportsNonprofit organization dedicated to consumer advocacy and product testingGo to source}
- Most cleaners should be diluted with water prior to use.
- Make sure to test the cleaner on a small, unnoticeable portion of your car's floor first to make sure it's safe to use on your car's interior.

Wipe down any non-carpeted surfaces. In addition to cleaning the carpet, wipe down any non-carpeted surfaces like the dashboard. Remove any spills and stains from these areas using a non-purpose cleaner.
- You should test any cleaner you use on a small, inconspicuous portion of the car first to make sure it doesn't cause damage.

With time, a car's air conditioner vents build up dirt and debris that can cause an unpleasant smell in your car. Make sure to treat the AC while deodorizing your car. Buy an AC cleaner made for cars at a local hardware store. Spritz down the vents of the car's air conditioning system with the cleaner. This will help reduce bad smells.^{[5]XResearch source}
Simply fill a container with dryer sheets and place it somewhere in your car. Dryer sheets can help absorb unwanted odor and also give off a pleasant scent. After cleaning your car, placing dryer sheets in the car can help eliminate lingering odors.^{[6]XResearch source}
Mix equal parts white vinegar and water. Spritz this mixture onto any areas in your car that are producing a bad smell. Saturate the area and let the vinegar absorb into the car. Then, use a scrub brush or other cleaning tool to scrub out the vinegar mixture. This should leave the car smelling significantly fresher.^{[7]XResearch source}

Use a pet deodorizer on pet smells. Pet deodorizers are made with specific enzymes that are designed to lift and eliminate pet odors. Brands of pet deodorizers vary in how they are used, but most of them are spritzed onto a stain and left to sit for a specific time period. You then rinse the pet deodorizer out.^{[8]XResearch source}
- Make sure to test any pet deodorizer you're using on a small, unnoticeable area in your car first to make sure it doesn't cause a stain or damage your car.
Baking soda can work for a wide variety odors as it naturally lifts scents. All you have to do is sprinkle baking soda over areas in your car that smell. Let the baking soda sit for a few hours or overnight and then vacuum it up.^{[9]XResearch source}
Place seven ounces of coffee beans in a container and leave the container in your car. If you let the beans sit in your car, they should absorb some odor. You can also use coffee grounds, but these may spill and cause mess.^{[10]XResearch source}

Seeking Professional Assistance

A fishy smell may indicate antifreeze is leaking into your car. Smells that come from the heat or AC system may indicate mechanical problems. These issues could be dangerous and indicate your car needs repairs, so take your car to a mechanic if you're having trouble with these smells.^{[11]XTrustworthy SourceConsumer ReportsNonprofit organization dedicated to consumer advocacy and product testingGo to source}
If your car smells like gas, do not attempt to treat the issue on your own. This can be very dangerous, as it indicates a leak somewhere in the car. Do not drive your car. Instead, immediately contact a mechanic for advice.^{[12]XResearch source}

Seek professional treatment for tobacco smells. Tobacco scents can get into a car's interior and usually cannot be removed without professional help. Even thorough cleanings do not always lift tobacco smells. If your car smells like tobacco, you will need professional cleaning to lift the odor.^{[13]XResearch source}
- Keep in mind, even professional cleaning does not have a 100% success rate at lifting tobacco odor, especially if a car was driven for years by a heavy smoker.

Question
How do I clean headlights?

Community Answer
You can use toothpaste or a dryer sheet. Apply the toothpaste to a clean rag, then rub it in and wipe it off. Take the dryer sheet and rub it on the headlight. You can also use an electric buffer to apply both of these.

Question
I spilled a cheese and hamburger dip that went down under my front door where I can't get it out. Besides taking it to a detailer, is there anything I can do to get rid of the smell?

There are products on the market that might help. A chlorine dioxide spray or gas generator would work really well and a brand called Clobberizer is a good one to try. It worked to get rid of a spilt milk smell in our car!
