The Ultimate Guide to Car Odor Removal

Car Odor Removal

We all know that the car can be a haven for bacteria, mold, and other allergens. It’s also an area where pets often ride in their own fur or go to the bathroom on seat covers. All of this means that your car is ripe for odor problems. Remember that Karim's Mobile detailing offers carpet shampooing, interior cleaning, and car odor removal.

Odors are especially problematic because they affect you not just while you’re in the vehicle but when you get out too! Your clothes will take on the smell, and it might even transfer to your skin if there isn’t enough ventilation or airflow. And don't forget about driving with passengers who may have different sensitivities than you do! 

What should we do? There are so many products available today for odor removal that it can be difficult to determine which ones are worth your money. Some companies even use bogus claims for how well their products work and don’t have any scientific proof to back up the processes or ingredients that they use. What can you do?

For starters, it helps to understand what the different kinds of odors in cars are caused by. Here is an overview:

Smoke - From cigarettes, cigars, and actual fires! If there is a lingering odor from smoking, the smell must be addressed immediately because it could cause permanent damage to your vehicle's interior if not dealt with properly. Just like smoke in a house that builds up over time, smoke residue does the same inside your car. Be sure to wash everything because fabrics may also absorb odors.

Car Bacteria - Beneath the seats, in cracks and crevices, and other mostly hidden places are bacteria. This can be caused by pets or by people who don’t clean up after themselves. The smell is akin to mildew, but it will grow over time if not dealt with. Wash it all regularly!

Cat/Dog Fur – Pets have hair that traps odors, so even if they are no longer traveling in your car, there may still be lingering smells left behind. Use products like enzymatic cleaners for this problem because they’re designed to break down proteins, including pet hair.

Old Food – Containers that hold protein-rich foods such as meat or cheese become magnets for odors over time. They also provide the perfect environment for bacteria to grow and multiply, so be sure to wash those containers frequently or throw them away.

General Smells – There may be a combination of smells in your vehicle that have layered on top of each other and are difficult to sort through. For starters, air out your car as much as you can by opening windows when parked outside. Clean all surfaces with water-based products that are safe for all areas of your car and don’t leave behind any residue that could cause new odors to form.

There are many causes of odors in cars, including pets, smoking, and old food. The most common is due to bacteria. To remove these odors, you can use a combination of natural and non-natural products. Natural products include citrus-based cleaners that won't leave any residue that could cause new odors to form, whereas non-natural ones will. Non-natural cleaners are perfect for removing smoke and general smells because of the negative ions that negative ions can create. To prevent these odors from happening in the first place, it’s important to clean and air out your car regularly.

Here are a few ways to remove odors from your car using natural or non-natural cleaners: 

Non-Natural Products: Non-natural cleaners have been used for decades to remove smoke and general smells from cars. These can work well because of the negative ions created that cause certain molecules to come out of their hiding places.

Natural Products: Natural products include citrus-based cleaners that won't leave any residue that could cause new odors to form, whereas non-natural ones will. Non-natural cleaners are perfect for removing smoke and general smells because of the negative ions that negative ions can create. To prevent these odors from happening in the first place, it’s important to clean and air out your car regularly.

Air Out It: When you can, air out your car using the windows and taking it outside. This allows the fresh air to come in contact with all of the surfaces that could be causing odors inside your car. Also, open up any containers that may be holding smells if possible so they can get some fresh air as well.

 1) Car Bacteria – Beneath the seats, in cracks and crevices, and other mostly hidden places are bacteria. The smell is akin to mildew, but it will grow over time if not dealt with. Wash it all regularly and dry thoroughly.

2) Food – Food containers that contain the protein are perfect for holding odors over time. Throw them away or wash them frequently if you want to get rid of the odor. Otherwise, it will only keep getting worse with time.

3) Smoking – Smoke can stick to your carpets and upholstery, which is why people who smoke often try to shield themselves from secondhand smoke in public places. The smell itself tends to linger as well, but using an enzymatic cleaner should help remove any nicotine or non-tobacco-related smells left behind.

4) Carpeting – Air out your car as much as possible by opening windows when parked outside. Wash all surfaces with water-based products that are safe for all areas of your car and don’t leave behind any residue that could cause new odors to form.

5) Leather/Suede – Use a leather cleaner on your seats or carefully apply a mixture of baking soda, warm water, and liquid soap to scrub the surface. Rinse with warm water afterward and blot dry. Occasionally apply leather conditioner in between washings if you want to keep their softness.

6) Spills – Any substance can create an odor problem when it soaks into carpeting or upholstery, so it’s best not to leave anything lying around. Clean spills by using either an enzymatic product, white vinegar, or hydrogen peroxide, depending on the spill.

7) Odor Eliminator – Use an odor eliminator in areas where odors have become entrenched. These products work best at removing general mishaps, but don’t leave your car with a chemical smell afterward. Use sparingly and only as needed.

8) Clutter – Clean all of your storage areas regularly so they can be free from dust and smells. If it still seems to reek after washing, use a baking soda/warm water mixture or air out your car regularly.

9) Weather – Sun can deteriorate materials over time, especially leather seats and dashboard covers made from vinyl instead of cloth. Ensure all parts you want to keep looking their best is protected from UV rays and other weather elements.

10) Old Air Fresheners – If you still have an old air freshener scent lingering, replace it with one that has a lighter or different kind of aroma. The longer they sit in your car’s interior, the more embedded the smell will become, regardless of whether it’s pleasant or not.

11) Cigarette Odor – Regularly clean your upholstery and carpets to keep them free from cigarette odors, but if previously smoked upon surfaces are terrible, try soaking them in a pail filled with 1-gallon vinegar mixed with 16 ounces warm water for about 20 minutes before washing away as usual. Or use an enzymatic product specifically designed for this purpose.

12) Flowery Scented Products – Too much floral-scented product can leave behind a stale odor even once the smell has worn off from other sources. The best way to ensure these smells are gone is to make sure you use only as much as necessary when applying your products.

13) Grease/Oil – Car interiors often need washing if they have held onto oil and grease from fast food containers or other things. Try using Dawn dish soap mixed with warm water or Windex all-purpose cleaner, then blot dry and air out the car afterward to get rid of any lingering odors.

14) Natural Odor Removal – If none of these methods works on any specific odors that have developed over time, consider using a product designed to neutralize rather than mask odors. Citrus and other natural extracts are often used in these products, although the best options require you to ventilate your vehicle as much as possible after applying them.



First, make sure that your car is always clean. This is step number one to preventing future smells in your car. Remember to wash the inside and outside of your car now and then. Cleaning up spills as they happen can help with this too!

Second, air out your car when it's sitting outside. Opening windows will help clear out any lingering odors and bring fresh air inside. Granted, this isn't guaranteed to work if, but it's still worth a shot.

Third, do not smoke inside your car! The smell will stick around for a while and can be very difficult to get rid of. Instead, wait until you arrive at your destination to light up that cigarette.

Fourth, keep the fluid levels in check. You wouldn't want an empty oil pan to cause problems later on down the road because you left it unreplaced for so long, right? It's also equally important that fluids are topped off when they need to be topped off. This goes for everything from windshield wiper fluid in the winter months to transmission fluid running low during the summer months (and so on).

Fifth, keep your car clean. You wouldn't want to catch a dirty guy, so why would you let a dirty interior in your cargo on for so long? Wash the floor mats, vacuum the seats and wipe up marks from them just like normal. Remember that soap and water are typically needed to wash any fabric surfaces (like the seats). Still, leather seats may require specific cleaning products and time spent with a professional cleaner to restore them to their original state.

Sixth, avoid eating inside of your vehicle if you can help it! If you're going to eat something and then drive, afterward place those wrappers in bags before placing them in the trash can of your vehicle. Removing the trash before you go is going to help you with this as well.

Seventh, make sure that your windows are washed and clean. If they're dusty or dirty, then all of those outside smells are just locked right in! This will not only help things smell better inside, but it's also for your safety out on the road. You wouldn't want a rock to hit your windshield, now would you?

Eighth, stay away from perfumes and other products containing chemicals that may cause an odor. However much you like their scent, stick to the minimal application if possible to create new odors later on down the line.

Ninth, try leaving some baking soda around when it comes time to park your car for some time. There have been many instances where this method has worked for people to eliminate odors that develop in parked vehicles.

10th, spray an odor eliminator directly onto the carpeting of your car if you're having issues with smells there too. Be advised that if you need to do this more than once, it could be a sign that your vehicle needs some mechanical work or maintenance is done on it, which may include replacing the carpet itself.

11th, throw open your windows at night to bring fresh air into your car while you sleep. What's better than waking up in the morning and enjoying the smell of sunshine after having a good night's rest?



In this blog post, we've discussed some of the most common odors that come from your car. Whether it's coming from a spill on the floor or simply something you ate while parked outside last night, there are plenty of causes for these smells, and they're all unique to your vehicle. Thankfully, with so many different kinds of cleaners available out there today (both natural and not), getting rid of any odor is possible without much effort at all. Our advice if you want to keep these types of smells away is simple - keep yourself clean inside as well! Keep up with routine cleaning tasks like vacuuming and washing the seats to prevent future spills. If an issue arises, be sure to rely on either baking soda or one of many odor eliminator products available to help eliminate it before it becomes a bigger problem.
