In this post, we'll explore 7 easy and effective methods to remove odor from your car. These tried-and-true techniques will have your car smelling clean and inviting in no time. So, let's dive in and kick those nasty odors to the curb!

1. Identify the Source of the Odor

Let's face it, we've all been there. You hop in your car, ready to hit the road, and then it hits you - a bad smell. It's like a punch to the nose. You start to wonder, where is this stinky odor coming from?

I've had my fair share of experiences with bad car odors. From forgotten gym bags to spilled coffee, I've learned that the first step in getting rid of a bad smell is to identify the source.

Check for spills or stains

Take a good look at your car's interior, paying close attention to the seats, floor mats, and carpets. If you spot any spills or stains, that could be the culprit behind the bad smell.

Look for signs of mold or mildew

I once bought a used car that had a musty, mildew smell. It was so bad that I could barely stand to drive it. After some investigating, I discovered that the car had a leak, which had led to mold growth under the seats.

Mold and mildew thrive in damp, dark environments, so if you notice a musty smell in your car, it's worth checking for any signs of moisture or water damage. Check under the seats, in the trunk, and even in the spare tire well.

2. Clean and Vacuum the Interior

Once you've identified the source of the bad smell in your car, it's time to get cleaning. And I'm not talking about just a quick once-over with a rag. To really get rid of those stubborn odors, you need to deep clean your car's interior.

Remove and Wash Floor mats

Start by removing all of the floor mats from your car. Give them a good shake to remove any loose dirt or debris, then toss them in the washing machine (if they're machine-washable) or scrub them down with some soap and water.

I like to use a mixture of warm water and a mild detergent to really get my floor mats clean. Just make sure to let them air dry completely before putting them back in your car.

Vacuum Seats and Carpets Thoroughly

Next, grab your vacuum cleaner and go to town on your car's seats and carpets. Use the upholstery attachment to get into all of the nooks and crannies, and don't forget to vacuum under the seats and in the trunk. If you have fabric seats, you may want to use a carpet cleaner to really deep clean them.

Use an upholstery attachment for hard-to-reach areas

For those hard-to-reach areas like the crevices between your seats or the tight spots around your gear shift, use an upholstery attachment on your vacuum cleaner. These attachments are designed to fit into small spaces and can help you remove dirt and debris that's been hiding out of sight.

If you don't have an upholstery attachment, you can also use a crevice tool or even a soft-bristled brush to get into those tight spots. Just be sure to vacuum up any loose dirt or debris when you're done.

3. Use Baking Soda to Absorb Odors

Baking soda is like nature's toxin absorber. It's extremely porous, which means it can soak up even the most stubborn odors. And the best part? It's cheap and easy to use.

Sprinkle Baking Soda on Seats and Carpets

Start by sprinkling a generous amount of baking soda on your car's seats and carpets. Don't be shy - really coat them in the stuff. I like to use a fine-mesh sieve to evenly distribute the baking soda, but you can also just sprinkle it on by hand.

Make sure to get the baking soda into all of the crevices and corners of your car's interior. The more surface area you can cover, the better.

Let the Baking Soda Sit Overnight

Once you've coated your car's interior in baking soda, let it sit for at least a few hours, or even better - overnight. The longer the baking soda has to work its magic, the more odors it will be able to absorb.

If you're worried about the baking soda making a mess, you can always put down some towels or sheets to catch any excess. Just be sure to remove them before you vacuum up the baking soda.

Vacuum Up the Baking Soda the Next Day

After the baking soda has had plenty of time to absorb any bad smells, it's time to vacuum it up. Use a high-powered vacuum cleaner to thoroughly remove all of the baking soda from your car's interior.

Pay extra attention to the crevices and corners where the baking soda may have accumulated. You may need to go over some areas a few times to make sure you've gotten all of the powder.

4. Try White Vinegar or Coffee Grounds

If baking soda alone isn't cutting it, there are a couple of other natural odor absorbers you can try. White vinegar and coffee grounds are both great options for removing stubborn smells from your car.

Place a Bowl of White Vinegar in the Car Overnight

White vinegar is a natural deodorizer that can help neutralize even the toughest odors. To use it in your car, simply fill a small bowl with white vinegar and place it in your car overnight.

The vinegar will work to absorb any bad smells in your car's interior. Just be warned - your car may smell a bit like vinegar in the morning, but that smell will quickly dissipate once you remove the bowl and air out your car.

Put Fresh Coffee Grounds in the Car to Absorb Odors

Coffee grounds are another natural odor absorber that can work wonders in your car. Simply place a bowl of fresh, unused coffee grounds in your car and let them sit for a few hours or overnight.

The coffee grounds will absorb any bad smells, leaving your car smelling fresh and clean. Plus, you'll get to enjoy the pleasant aroma of coffee every time you get in your car.

5. Use an Air Freshener

Sometimes, even after a deep clean and using natural odor absorbers, your car may still have a lingering smell. That's where air fresheners and odor eliminators come in.

Hang an Air Freshener from Your Rearview Mirror

Air fresheners are an easy and affordable way to make your car smell great. Simply hang one from your rearview mirror or clip it to your car's air vent.

There are tons of different scents to choose from, so you can pick one that suits your preferences. Just be sure to replace the air freshener every few weeks to keep your car smelling fresh.

Try a Natural Air Freshener with Essential Oils

If you prefer a more natural approach, you can make your own air freshener using essential oils. Simply add a few drops of your favorite essential oil to a small spray bottle filled with water.

Spritz the mixture around your car's interior, focusing on the seats, carpets, and air vents. Some great essential oils for freshening up your car include lemon, lavender, and eucalyptus.

6. Consider an Ozone Generator or Professional Service

If you've tried all of the above methods and your car still smells less than fresh, it may be time to bring in the big guns. Ozone generators and professional odor removal services can help eliminate even the most stubborn smells.

Use an Ozone Generator to Neutralize Odors

Ozone generators work by producing ozone, a gas that can neutralize odors and kill bacteria and mold. Our portable air purifier can be used in closets, gym bags, and yep - you guessed it.. cars. 

Hire a Professional Odor Removal Service for Tough Odors

If you're dealing with a particularly stubborn odor or just don't have the time or energy to tackle it yourself, consider hiring a professional odor removal service. These companies have the tools and expertise to eliminate even the toughest smells.

Look for a company that uses eco-friendly and non-toxic products, and be sure to read reviews before hiring anyone. A reputable odor removal service should be able to get your car smelling fresh and clean in no time.

7. Prevent Future Odors

Once you've gotten rid of the bad smells in your car, you'll want to take steps to prevent them from coming back. Regular cleaning and maintenance can go a long way in keeping your car smelling fresh.

Regularly Clean and Vacuum Your Car's Interior

Make it a habit to clean and vacuum your car's interior on a regular basis. I try to do a quick clean-up every week, and a more thorough deep clean once a month.

Focus on high-traffic areas like the driver's seat and floor mats, and don't forget to clean out any trash or debris that may have accumulated. Regular cleaning will help prevent odors from building up over time.

Change Cabin Air Filters Periodically

Your car's cabin air filter helps remove dust, pollen, and other airborne particles from the air inside your vehicle. Over time, these filters can become clogged and less effective at trapping odors.

Check your car's owner's manual to see how often the cabin air filter should be changed, and be sure to replace it as recommended. A fresh air filter can make a big difference in the overall smell of your car.

Avoid Smoking or Transporting Strong-smelling Items In your car

One of the best ways to prevent bad smells in your car is to avoid bringing them in in the first place. If you smoke, try to do so outside of your vehicle, and avoid transporting strong-smelling items like gasoline or cleaning products in your car.

If you do need to transport something smelly, be sure to remove it as soon as possible and air out your car thoroughly afterwards. A little prevention can go a long way in keeping your car smelling fresh and clean.


There you have it, folks - 7 simple yet effective ways to remove odor from your car. From the all-natural power of baking soda and essential oils to the high-tech wizardry of ozone generators, you've got plenty of options to choose from.

Remember, the key to keeping your car smelling fresh is regular maintenance. Vacuum those carpets, wipe down those surfaces, and don't let spills or stains linger. With a little TLC and these odor-busting techniques in your arsenal, you'll be cruising in a clean, fresh-smelling ride in no time.

So go ahead, try out these methods, and see which ones work best for you. Your nose (and your passengers) will thank you!
